Description

Glycopegylated method and the proteins/peptides of producing by this method

Background of invention

Most of naturally occurring peptides contain on the length of one-level peptide chain by the amino acid whose specific bonding with selected number and are attached to carbohydrate part on the peptide.Thereby many naturally occurring peptides are called " glycopeptide ".The changeability of the glycosylation pattern on any given peptide has huge meaning for the function of this peptide.For example, the structure of the glycan of N-connection can influence the various features of peptide on the peptide, comprises the interior transportation of protease susceptibility, cell, secretion, tissue orientation, biological half life period and the antigenicity of peptide in cell or the biology.The change of one or more of these features has influenced the effect of peptide in its natural surroundings widely, and has also influenced peptide as the effect of therapeutic agent in certain situation, and this peptide promptly generates for this purpose in this situation.

The carbohydrate structure that is attached on the peptide chain is known as " glycan " molecule.The specific glycan structures that exists on peptide influences resistance that the folding and function of the solubility of this peptide and aggregation characteristic, one-level peptide chain or enzymic activity, this peptide attack proteolysis and the proteoclastic control that the inactive form that causes peptide is changed to activity form.Importantly, be present in the length that terminal sialic acid residues on the glycan molecule influences the half life period of peptide in the mammal circulatory system.The peptide that its glycan does not contain terminal sialic acid residues will be removed from circulation fast by liver, and this is the incident that any potential treatment benefit of peptide was lost efficacy.

The glycan structures that natural discovery is present on the glycopeptide generally is divided into two classes, and promptly N-connects is connected with O-.

The peptide of in eukaryotic, expressing generally be on the site of peptide primary structure on asparagine residue N-glycosylated, the sequence of asparagine-X-serine/threonine is contained in this site, wherein X can be any amino acid except that proline and aspartic acid.Carbohydrate in this peptide partly is known as the glycan that N-connects.The glycosylated early stage incident of N-betides in the endoplasmic reticulum (ER) and is identical in mammal, plant, insect and other higher eucaryotes.At first, the oligonucleotide chain that comprises 14 saccharide residues makes up on lipid carrier.When nascent peptide translation and transposition entered ER, whole oligonucleotide chain was then transferred in the reaction of membrane-bound glycosyl transferase catalysis on the amide group of asparagine residue.The glycan that N-connects is further processed in ER and Golgi body.Further processing need be removed some saccharide residues usually and be added other saccharide residue in by the reaction of glycosidase and glycosyl transferase catalysis, wherein said enzyme is specific for the saccharide residue of removing and add.

Usually, the final structure of the glycan of N-connection depends on the biology that produces this peptide.For example, bacteriogenic peptide complete sugar basedization normally.Contain oligonucleotide chain that high mannose is connected with paunci-mannose N-and other at the peptide of expressed in insect cells.The peptide that produces in the mammalian cell cultures depends on usually as species and cell culture condition and glycosylation differentially.Even in identical species,, also run into some heterogeneity in the glycosyl chain sometimes with under identical condition.Further, the peptide that produces in the plant cell comprise significantly with those zooblasts in the different glycan structures that produces.Predicament in the field that produces recombinant peptide (particularly when this peptide is used as therapeutic agent) is to generate correct glycosylated peptide, promptly can generate have with the native form that is present in peptide in the peptide of similar or identical glycan structures.The peptide that most of recombination methods produce comprises the glycan structures different with naturally occurring glycan.

Proposed the glycosylation pattern that several different methods customizes peptide in the art, comprised that those are described in WO 99/22764, WO 98/58964, WO 99/54342 and the U.S. Patent No. 5,047,335, and other.Basically, the necessary many enzymes of the external glycosylation of peptide are cloned and check order.In some cases, these enzymes add specific sugar on the peptide incomplete glycan molecule in external being used for.In other situations, cell has carried out the combination of gene engineering processing with expression enzyme and the peptide of wanting, thus the interpolation of the sugar moieties that can in cell, want in the peptide of expressing.

Peptide also can be modified by the glycan that adds the O-connection, and this glycan is because its ubiquity on the mucoprotein glycopeptide is also referred to as the glycan of mucoprotein type.Be connected to asparagine residue on and to shift the N-glycan that oligosaccharides forms by integral body from the intermediate of lipid combination different, the O-glycan mainly is connected on serine and the threonine residues and by the sugar that progressively adds from the nucleotide carbohydrate and forms (people such as Tanner, Biochim.Biophys.Acta.906:81-91 (1987); With people such as Hounsell, Glycoconj.J.13:19-26 (1996)).The O-that the peptide function can be subjected to existing thereon connects the influence of glycan structures.For example, P-selects the activity of protein ligands to be subjected to the influence of the O-connection glycan structures of existence on it.For the summary of O-connection glycan structures, referring to Schachter and Brockhausen, The Biosynthesis ofBranched O-Linked Glycans, 1989, Society for ExperimentalBiology, pp.1-26 (Britain).Other glycosylation patterns form (people such as Takeda, TrendsBiochem.Sci.20:367-371 (1995) by connect glycosyl-phosphatidyl inositol to protein carboxyl terminal carboxylic group; With people such as Udenfriend, Ann.Rev.Biochem.64:593-591 (1995)).

Although exist the N-of various modified peptides to connect the technology of glycan at present, this area need generate the universal method of peptide, and this peptide has the i.e. glycosylation pattern of wanting of customization.This area needs the external glycosylation of the customization (Customize) of peptide especially, and wherein the peptide of gained can be produced on commercial scale as a result.The present invention can satisfy this and other needs.

Giving glycosylation and nonglycosylated peptide is that field of medicaments is well-known to produce specific physiological responses.One of the most well-known peptide that is used for this purpose is an insulin, and it is used for the treatment of diabetes.Enzyme also uses because of its treatment benefit.The principal element that has limited the application of therapeutic peptide is the immunogenicity characteristic of most of peptides.In the patient, to the immunogenic response of the peptide that gives can in and peptide and/or cause allergic development among the patient.Other deficiencies of therapeutic peptide comprise inferior optimum effectiveness and clearance rate fast.Have recognized that the problem that peptide therapeutics is intrinsic in the art, and studied the method for the described problem of various eliminations.For the peptide therapeutics of solubility is provided, synthetic polymer is attached on the peptide main chain.

Poly-(ethylene glycol) (" PEG ") is the exemplary polymer of puting together with peptide.Proved and used PEG to make the peptide therapeutics derivatization can reduce the immunogenicity and the checkout time of prolongation from circulation of peptide.For example, U.S.Pat.No.4,179,337 (people such as Davis) relate to the peptide of non-immunogenicity, as with the enzyme and the peptide hormone of polyethylene glycol (PEG) or polypropylene glycol coupling.Every mole of peptide has used 10～100 moles polymer and has kept at least 15% physiologically active.

WO 93/15189 (people such as Veronese) relates to by keeping the method for polyethyleneglycol modified hydrolase of proteolysis on the inhibitor that proteolytic enzyme is connected to big molecularization.This conjugate is intended for use in medical application.

The main pattern that PEG and derivative thereof adhere to peptide is the unspecific connection by the peptide ammino acid residue.For example, U.S. Patent No. 4,088,538 disclose the enzymic activity polymer-enzyme conjugate with the covalently bound enzyme of PEG.Similarly, U.S. Patent No. 4,496,689 disclose the compound of α-1 protease inhibitors and polymer such as PEG or poly-(ethylene glycol) (" mPEG ") covalent attachment of methoxyl group.People such as Abuchowski (J.Biol.Chem.252:3578 (1977)) disclose the covalent attachment of the amine groups of mPEG and bovine serum albumin(BSA).U.S. Patent No. 4,414,147 disclose by with the acid anhydrides of itself and the dicarboxylic acids method that makes the interferon hydrophobicity lower of puting together as poly-(ethene succinyl oxide).PCT WO 87/00056 discloses puting together of PEG and polyoxy ethylization polyalcohol and proteins such as interferon-beta, interleukin 2 and immunotoxin.EP 154,316 discloses and asks for protection the lymphokine of chemical modification as containing the IL-2 of the PEG that directly is connected with at least one one-level amino group of lymphokine.U.S. Patent No. 4,055,635 disclose the pharmaceutical composition of the proteolytic enzyme water-soluble compound that is connected with polymeric material such as polysaccharide covalent.

The another kind of pattern that PEG and peptide adhere to is the unspecific oxidation by glycosyl residue on the peptide.The sugar of oxidation can be used as peg moiety is attached to seat on the peptide.For example, M ' Timkulu (WO94/05332) discloses hydrazine-PEG or amino-PEG and has added PEG on the glycoprotein application.Glycosyl part is oxidized to corresponding aldehyde randomly, and subsequently with amino-PEG coupling.Also referring to people such as Bona (WO 96/40731), wherein glycan is contacted with amino-PEG molecule and PEG is added on the immunoglobulin molecules by the glycan on the enzymatic oxidation immunoglobulin.

In above-mentioned each method, poly-(ethylene glycol) is to add on the reactive residue of peptide main chain in nonspecific mode at random.For the peptide of manufacture of therapeutic, what obviously want is a kind of derivatization strategy, and this strategy causes the formation of the product of specific markers, that be easy to characterize and basic homogeneous.

In carbohydrate is synthetic, use the main enzyme of two classes, i.e. glycosyl transferase (as sialyltransferase, oligosaccharyl transferase, N-acetyl-glucosamine transferase) and glycosidase.Glycosidase is further divided into exoglycosidase (as beta-Mannosidase, β-Pu Tangganmei) and endoglycosidase (as Endo-A, Endo-M).Each of these several fermentoids is successfully synthesized and is used to prepare carbohydrate.For general summary, referring to people such as Crout, Curr.Opin.Chem.Biol.2:98-111 (1998).

Oligosaccharide structure on the glycosyl transferase modified peptides.Glycosyl transferase is effective for producing specific product with good spatial chemistry and regional chemistry (regiochemical) control.Glycosyl transferase has been used to prepare oligosaccharides and has been used to modify terminal N-or carbohydrate structure that O-is connected, particularly on the peptide of mammalian cell generation.For example, the sialylated fully and/or fucosylation of the terminal oligosaccharides of glycopeptide provides firmer sugared structure, and this has improved the pharmacokinetics and various other the biological property of glycopeptide.For example, β-1,4-galactosyltransferase can be used for synthetic lactose amine, and this is that glycosyl transferase is used for a synthetic example of carbohydrate (referring to as people such as Wong, J.Org.Chem.47:5416-5418 (1982)).In addition, many synthesis programs use α-sialyltransferases with sialic acid from Cytidine-5 '-single phosphoric acid-N-n acetylneuraminic acid n transfers to the 3-OH of galactose or 6-OH (referring to as people such as Kevin, Chem.Eur.J.2:1359-1362 (1996)).Fucosyltransferase can be used for route of synthesis so that fucose unit is transferred on the specific hydroxyl of saccharide acceptor from guanosine-5 '-diphosphonic acid fucose.For example, Ichikawa has prepared saliva acid Lewis-X people such as (, J.Am.Chem.Soc.114:9283-9298 (1992)) Ichikawa by the method that relates to sialylated lactose amine and carry out fucosylation by clone's fucosyltransferase.For the discussion of the synthetic nearest progress of the glycoconjugate that is used for the treatment of purposes, referring to people such as Koeller, Nature Biotechnology 18:835-841 (2000).Also referring to U.S. Patent No. 5,876,980,6,030,815,5,728,554,5,922,577 and WO/9831826.

Glycosidase also can be used for preparing carbohydrate.The hydrolysis of the common catalysis glycosidic bond of glycosidase.Yet under proper condition, they can be used for forming this key.Being used for the synthetic most of glucosides enzymes of carbohydrate is exoglycosidases; Glycosyl shifts the non-reduced end that betides substrate.In conjunction with glycosyl donor, hydrolysate be got and be produced to this intermediate can by the water misfortune to glycosidase, or get generation new glucosides or oligosaccharides by the acceptor misfortune in glycosyl-enzyme intermediate.An exemplary approach using exoglycosidase is core trisaccharide synthetic of the glycopeptide that connects of all N-, comprises β-mannose glycosidic bond of being formed by beta-Mannosidase effect people such as (, Chem.Commun.993-994 (1996)) Singh.

In using glycosidase another exemplary application with the formation glycosidic bond, prepared the glycosidase of sudden change, wherein the normal nucleophilic amino acid change of avtive spot is non-nucleophilic amino acid.The enzyme of this sudden change is the hydrolysis sugar glycosidic bond not, but still can form this key.The glycosidase of this sudden change can be used for preparing oligosaccharides (people such as Withers, U.S. Patent No. 5,716,812) with alpha-glycosyl fluoride donor and glucosides acceptor molecule.

Be not so good as the general of exoglycosidase although it is used, endoglycosidase also is used to prepare carbohydrate.Has the advantage of transferable oligosaccharides rather than monose based on the method for using endoglycosidase.Oligose fragment has been added on the substrate to (people such as Wang, Tetrahedron Lett.37:1975-1978) with endo-β-N-acetyl-glucosamine such as endo-F, endo-M; With people such as Haneda, Carbohydr.Res.292:61-70 (1996)).

Except that its application of preparation carbohydrate, above-mentioned enzyme also can be applicable to synthetic glycopeptide.Delivered synthetic people such as (, J.Am.Chem.Soc.119:2114-2118 (1997)) the Witte K. of the homogeneous sugar form (glycoform) of ribonuclease B.The high mannose core of ribonuclease B can be cut by handling glycopeptide with endoglycosidase H.This cutting specifically betides between two core GlcNAc residues.Then by using β-1 successively, 4-galactosyltransferase, α-2,3-sialyltransferase and α-1, the 3-fucosyltransferase, tetrose saliva acid Lewis X can rebuild by enzymatic on remaining GlcNAc anchored site on the protein of homogeneous.Yet although each enzymatic step is all carried out with fabulous output, this program can not be applicable to and generate glycopeptide on commercial scale.

Method in conjunction with chemistry and enzymatic synthesis element also is as known in the art.For example, Yamamoto and colleague (Carbohydr.Res.305:415-422 (1998)) have reported with endoglycosidase synthetic to the chemical enzymatic (chemoenzymatic) of glycopeptide, glycosylated peptide T.The N-acetyl-glucosamine peptide is synthetic by chemical method fully.This peptide carries out the enzyme processing with the oligosaccharides of human transferrin peptide subsequently meticulously.Sugar moieties adds on the peptide by handling with endo-beta-N-acetyl aminoglucose enzyme (acetylglucosaminidase).The glycosylated peptide of gained and peptide T compare with N-acetyl-glucosamine peptide T and are high stability and proteolysis had resistance as a result.

Also probed into the application of the glycosyl transferase that is used to modify peptide structure with reporter group.For example, people such as Brossmer (U.S. Patent No. 5,405,753) application in the fluorescence labeling of measuring sialyltransferase active and cell surface, glycoprotein and peptide of the formation of sialic fluorescently-labeled cytidine monoposphate (" CMP ") derivative and fluorescence glucosides is disclosed.People such as Gross (Analyt.Biochem.186:127 (1990)) have described similar mensuration.People such as Bean (U.S. Patent No. 5,432,059) disclose and have utilized the glycosylation again of the insufficient glycosylated protein mensuration to the glycosylation defect illness.This deficient protein matter is glycosylated again with fluorescently-labeled CMP glucosides.Each fluorescence sialic acid derivative all partly replaces on common acetylizad 9-position or the amine in sialic acid with fluorescence.The method of using the fluorescence sialic acid derivative is the mensuration whether nonglycosylated or incorrect glycosylated glycoprotein of glycosyl transferase is existed.This mensuration is in the sample of biological origin a spot of enzyme or glycoprotein to be carried out.Sialic acid still unexposed or that proposition utilization is modified carries out the enzymatic derivatization with preparation or commercial scale to glycosylated or nonglycosylated peptide in the prior art field.

Also existing considerable effort relates to by changing the glycosyl residue that is presented by cell surface modifies this cell surface.For example, Fukuda and colleague have been developed the method that the glucosides that will have limiting structure is attached to cell surface.This method is utilized the undemanding substrate specificity of fucosyltransferase, the transferable fucose of this enzyme and have fucose analog people such as (, J.Biol.Chem.271:27213 (1996)) Tsuboi of different sugar substrate.

Enzymatic method also has been used to activate glycosyl residue on the glycopeptide to help chemical treatment subsequently.Generally with the galactose oxidase activation, this enzyme changes terminal galactose residues into corresponding aldehyde to glycosyl residue.This aldehyde subsequently with the modification group coupling that contains ammonia.For example, people (Nature Biotech.19:142 (2001)) such as Casares has been attached to adriamycin on the galactose residue of the chimeric oxidation of MHCII-peptide of reorganization.

Also glycosyl residue is modified so that it contains ketone groups.For example, Mahal and colleague (Science 276:1125 (1997)) have prepared N-acetyl propionyl mannosamine (" ManLev "), and the position that it is occupied by acetyl group in natural substrate usually has ketone.Handle cell with ManLev, thereby ketone groups is integrated into cell surface.Also referring to people such as Saxon, Science 287:2007 (2000); People such as Hang, J.Am.Chem.Soc.123:1242 (2001); People such as Yarema, J.Biol.Chem.273:31168 (1998); With people such as Charter, Glycobiology 10:1049 (2000).

The method of modifying cell surface is not applied to modify glycosylated or nonglycosylated peptide as yet when not having cell.Further, the cell surface method of modifying glycosyl donor part enzymatic that is not used for modifying is integrated into peptide.In addition, not having a kind of cell surface method of modifying is feasible in the peptide glycosyl modified with industrial-scale production.

Although the effort that relates to sugared structure enzymatic treatment is arranged, but still need industrial feasible method to be used for glycosylated and nonglycosylated peptide being modified this modification group such as water-soluble polymer, treatment part, biomolecule etc. with modification group.Interested especially is the method that the peptide wherein modified has the characteristic of improvement, and the characteristic of this improvement has strengthened the application of this peptide as treatment or diagnosticum.The present invention has satisfied the needs of these and other.

In its native form, the glycopeptide that N-of the present invention connects is to carry out N-with the three mannose core textures that adhere to one or more sugar thereon to be connected glycosylated especially for mammal of the present invention and human glycopeptide.

Term " glycopeptide " and " sugared polypeptide " are used in reference to the peptide chain with the sugar moieties that adheres to thereon with the free burial ground for the destitute herein.Herein little sugared polypeptide or glycopeptide and big sugared polypeptide or glycopeptide are distinguished.Thereby hormone molecule and other very large peptides of having considerably less amino acid (as usual few to 3 amino acid) in its peptide chain are included in generic term " sugared polypeptide " and " glycopeptide ", as long as they have the sugar moieties that adheres to thereon.Yet the using of term " peptide " do not got rid of this peptide and is glycopeptide.

Example with glycosylated N-connection glycopeptide of wanting is the peptide with glycan of N-connection, and this glycan has the three mannose cores of adhering at least one GlcNAc residue thereon.This residue adds on the three mannose cores with N-acetyl-glucosamine transferase I (GnT-I).If add second GlcNAc, then use N-acetyl-glucosamine transferase I I (GnT-II).Selectively, available GnT-IV and/or GnT-V add extra GlcNAc residue, and the GlcNAc residue of the 3rd five equilibrium can be attached on β 1,4 mannose of three mannose cores with N-acetyl-glucosamine transferase I II (GnT-III).Selectively, this structure can be handled to extend with the GlcNAc to each non-five equilibrium and go up the interpolation galactose residue with β 1,4 galactosyltransferase, and further selectively, utilize α 2,3 or α 2, the 6-sialyltransferase can add sialic acid residues on each galactose residue to.The GlcNAc of five equilibrium is not to add galactose subsequently and sialic acid residues is necessary to the interpolation of glycan; Yet for the substrate affinity of rat and human GnT-III enzyme, the interpolation of the GlcNAc of five equilibrium has been got rid of in the existence of one or more galactose residues on the glycan, and this is because the glycan that contains galactose is not the substrate of the GnT-III of these forms.Thereby, want to exist and use under the situation of GnT-III of these forms at the GlcNAc of five equilibrium, importantly contain the galactose and/or the sialic acid of interpolation as levulan, they should be removed before the GlcNAc that adds five equilibrium so.The activity of other forms of GnT-III may not need this specific substrate order.In preferred reaction, the mixture of GnT-I, GnT-II and GnT-III is joined in the reactant mixture, thereby the GlcNAc residue can add with any order.

Representative has in the accompanying drawing that the example of glycan structures of various aspects of the peptide of " glycosylation of wanting " provides herein and shows.External generation has the accurate process of the peptide of " glycosylation of wanting " and describes elsewhere.Yet the present invention never should be interpreted as just being confined to disclosed herein any one glycan structures.The present invention more suitably should be interpreted as comprising any one or the whole glycan structures that can be used on method provided herein preparation.

In some cases, basic three mannose cores can constitute the glycosylation of wanting of peptide separately.For example, shown that the peptide that only has three mannose cores is useful component (people such as Mistry, 1966, the Lancet 348:1555-1559 that is used for the treatment of the enzyme of familial splenic anaemia; People such as Bijsterbosch, 1966, Eur.J.Biochem.237:344-349).

According to the present invention, generation is described below has the program of the glycosylated peptide of wanting.

A) originate in glycopeptide with one or more glycan molecules, the common trait of this glycan molecule is to have three mannose core textures and the mixture that is at least a or multiple heterogeneous or homogeneity of one or more sugar of adding thereon, possible is increase have three basic mannose core textures as unique glycan structures or have Man3GlcNAc3 or Man3GlcNAc4 a ratio as the glycopeptide of unique glycan structures.This is by systematically realizing that to the enzyme of glycopeptide interpolation proper number the mixture heterogeneous or homogeneity that this enzyme can cut the sugar on the glycan structures reduces to basic three mannose cores or Man3GlcNAc3 or Man3GlcNAc4 structure up to it with suitable order external.These specific examples how to realize will depend on various factors, comprise cell type that produces peptide and the complexity degree of the glycan structures that therefore exists on very most of on the peptide that is produced by cell at first.How complicated glycan structures is reduced to basic three mannose cores or Man3GlcNAc3 or Man3GlcNAc4 example of structure shows in Fig. 2, or has a detailed description elsewhere.

B) possible is to generate by the cell that separating natural exists to have the peptide of three basic mannose core textures as unique glycan structures, and wherein the glycosylation machine of this cell produces this peptide.The DNA transfection of the target peptide of will encoding then in cell, therein DNA transcribe, translation and glycosylation, thereby target peptide has three basic mannose core textures as unique glycan structures.For example, shortage has the cell of the GnT-I enzyme of function will produce the glycopeptide of several types.In some cases, these will be not have the glycopeptide that is attached to the extra sugar on the three mannose cores.Yet under other situation, the peptide of generation can have 2 extra mannose residues that are attached on the three mannose cores, thereby the result obtains the Man5 glycan.This also is the starting material of wanting that is used for restructuring procedure of the present invention.The specific examples that generates this glycan structures is described herein.

C) selectively, possible is that pair cell carries out gene engineering processing to give this cell specific glycosylation machine, has basic three mannose cores or Man3GlcNAc3 or the Man3GlcNAc4 structure peptide as unique glycan structures on the peptide thereby can produce.The DNA transfection of the target peptide of will encoding then in cell, therein DNA transcribe, translation and glycosylation, thereby target peptide has the glycan that comprises three basic mannose core textures separately that increases number.For example, the cell that carries out gene engineering processing and lack some type of GnT-I has generation the glycan of three basic mannose core textures, perhaps depend on this cell, can produce the glycan (Man5) of 2 extra mannose residues that have three mannose cores and adhere to thereon.When cell produces the Man5 glycan structures, but pair cell further carries out gene engineering processing to express

mannosidase

3, and 2 extra mannose residues of these mannosidase 3 cuttings are to generate three mannose cores.Selectively, the Man5 glycan can carry out incubation to reach identical effect with mannosidase 3 external.

D) when peptide during in expressed in insect cells, the glycan on the peptide comprises the compound chain of part.Insect cell is also expressed hexosaminidase in cell, this enzyme chain that part is compound is trimmed to three mannose core textures, and this structure is reconstructed as described in herein then.

E) from b), c) and d) discussion see and it is evident that cell does not need only to produce the peptide that is attached with basic three mannose cores or Man3GlcNAc3 or Man3GlcNAc4 structure thereon.Unless that more suitable is b) and c) in the cell described produce and have 100% basic three mannose core textures (promptly not having the extra sugar that adheres to thereon) or 100% Man3GlcNAc3 or Man3GlcNAc4 structure, cell in fact produces the heterogeneous mixture of peptide, this peptide except that the combination with basic three mannose core textures or Man3GlcNAc3 or Man3GlcNAc4 structure as unique glycan structures, also have these structures that are attached with other sugar thereon.Peptide with the three mannose cores that are attached with extra sugar thereon or Man3GlcNAc3 or Man3GlcNAc4 structure will depend on the cell that produces them to those ratios that only have a kind of peptide of structure and change.The complexity of glycan (being which kind of and how much sugar are attached on the three mannose cores) also will depend on the cell that produces them.

F) in case pass through a) according to the present invention, b) or c) produced the glycopeptide that has three basic mannose cores or be attached with three mannose cores of one or more GlcNAc residues thereon, have the glycosylated peptide of wanting (promptly having peptide) external extra glycan molecule can being added on the three mannose core textures with generation so at the glycan structures of external customization.

G) yet, be attached with some thereon but when not being the peptide of the basic three mannose cores of the sugar all wanted or Man3GlcNAc4 structure when having produced to have, so only need to add the remaining sugar of wanting, and glycan structures need not be reduced to basic three mannose cores or Man3GlcNAc4 structure.Therefore, in some cases, the peptide with glycan structures of the three mannose core textures that are attached with extra sugar thereon will be the suitable substrate that is reconstructed.

The separation of basic three mannose core glycopeptides

If desired, basic three mannose cores of the present invention or Man3GlcNAc3 or Man3GlcNAc4 glycopeptide can separate and purifying with the well-known technology in peptide purification field.Suitable technology comprises chromatographic technique, isoelectric focusing technique, hyperfiltration technique etc.Utilize any such technology, can prepare composition of the present invention, glycopeptide wherein of the present invention is to be typically found at component separation in the cell culture medium with other peptides with other.With respect to other peptide, the degree of purifying can be as 90% or 95% or higher, as 98%.Referring to as people such as Deutscher (ed., 1990, Guide to Protein Purification, Harcourt Brace Jovanovich, San Diego).

Be present in the heterogeneous separation that only allows fraction target glycopeptide usually that N-in the glycopeptide that is produced by the method in prior art field connects glycan, this target glycopeptide can be modified the glycopeptide of wanting with generation.In the method for the invention, can produce a large amount of basic three mannose core glycopeptides and other glycopeptides of wanting, comprise Man3GlcNAc3 or Man3GlcNAc4 glycopeptide, these glycopeptides can further be modified then to generate has the glycosylated peptide of wanting in a large number.

Shown a series of possible vitro reactions in Fig. 7, this reaction can be carried out the pruning of the glycan that originates in high mannose structures and interpolation.For example, the Man9 glycan can be pruned generating the Man5 glycan with mannosidase 1, or its available mannosidase 3 or one or more microorganism mannosidases are trimmed to three mannose cores.Then can with GnT-I and or GnT-II be used for extra GlcNAc residue is transferred to glycan.Further, shown the situation (referring to dash box) that when the glycan molecule produces, does not take place in the cell that does not have GnT-I.For example, fucose and wood sugar only can add on the glycan when GnT-I is active and promotes GlcNAc to the transfer of molecule.

Fig. 8 describes and to originate in synthetic two feeler, three feelers and even the well-known strategies of the glycan structures of four feelers of three mannose core textures.The method according to this invention, possible is with each in external synthetic these structures of well-known suitable enzyme and reaction condition in the glycobiology field.

Fig. 9 describes two kinds of methods that begin synthetic single feeler glycan structures from high mannose (6～9 mannose parts) glycan structures.According to Glycopegylated method described herein, can add terminal sialic acid-peg moiety to substitute the sialic acid part.In first method, endo-H is used for the glycan structures on the peptide is cut to first GlcNAc residue.Add galactose with galactosyltransferase then, and add sialylated PEG as described elsewhere herein.In second method, mannosidase I is used for the glycan structures cutting mannose residue from peptide.Galactose residue is added on the arm of remaining mannose residue, this mannose residue excises from glycan with the sword bean alpha-Mannosidase.The PEG with sialylated as described adds on this structure then.

Figure 10 describes the other two kinds of methods that begin synthetic single feeler glycan structures from high mannose (6～9 mannose parts) glycan structures.The same with among Fig. 9 according to Glycopegylated method described herein, added terminal sialic acid-peg moiety to substitute the sialic acid part.In the described herein situation, never add the arm of sialylated PEG and remove some mannose residues.

In Figure 11, shown the scheme that originates in the synthetic more complicated sugared structure of three mannose core textures.For example, the sialylated or non-sialylated Lewisx of produced in vitro and the scheme of Lewi s a antigenic structure have been shown.This structure can give peptide immunologic advantage on being present in peptide the time, regulates immune response to be used for incremental adjustments or decrement.In addition, this structure can be used for the guiding of peptide to specific cells, and this is because this class formation participates in and the combining of cell attachment peptide etc.

Figure 12 is the exemplary arrangement that is used to prepare the peptide array of the O-connection that is derived from serine or threonine.

Figure 13 is the diagram that a series of descriptions are called the glycan structures that 4 class O-of core 1～4 connect.Core texture is described with dotted line.The steamed bun stuffed with sugar that also can be included in this structure is drawn together sialic acid residues that adds on the galactose residue and the fucosyl residues that adds on the GlcNAc residue.

Thereby, in preferred embodiments, the invention provides the method for the glycosylation glycopeptide of preparation N-connection, this method is: separation and glycopeptide purifying that has adhered to basic three mannose cores or Man3GlcNAc4 structure thereon is provided, glycopeptide and glycosyl transferase and the donor molecule with glycosyl part are contacted under the condition that is suitable for glycosyl part transferred in the glycopeptide.Customize three basic mannose cores or Man3GlcNAc4 structure then and have the peptide of the glycosylation pattern of wanting with generation, this can realize by adding the sugar moieties of wanting successively with technology well known in the art.

When the glycopeptide of N-connection is produced by cell, as mentioning elsewhere, it can comprise the heterogeneous mixture of glycan structures, and this glycan structures must be reduced to total and common basic three mannose cores or Man3GlcNAc4 structure before the sugar moieties that adds other on it.Which sugar should be removed from specific glycan structures in order accurately to determine, essential sometimes is to identify the one-level glycan structures.The technology of determining the glycan primary structure is well known in the art, and be described in detail in as Montreuil, " Structure and Biosynthesis ofGlycopeptides ", Polysaccharides in Medicinal Applications, pp.273-327,1996, Eds.Severian Damitriu, Marcel Dekker, NY.Therefore separation is a simple thing by peptide colony and the definite glycan structures that adheres to thereon that cell produces for the technical staff in the glycobiology field.For example, for lower part available effective ways are arranged: (i) make the glycosidic bond fracture by chemical cleavage such as hydrolysis, acetic anhydride decomposition, hydrazinolysis or by the nitrous acid deamination; (ii) exhaustive methylation is hydrolyzed or Methanol Decomposition and carry out gas liquid chromatography and mass spectrometry analysis to the monose of part methylization subsequently subsequently; (iii) with exoglycosidase to the determining of different key between the monose, this also provides understanding to the one-level glycan structures by degraded successively.Especially, mass spectrometry and nuclear magnetic resonnance (NMR) spectrum determination method particularly the NMR of High-Field can successfully be used for determining the glycan primary structure.

Be used for the kit of glycan analysis and equipment is also commercial buys.Sugared electrophoresis (the FACE that fluorogen is auxiliary ^_) can be available from Glyko, Inc. (Novato, CA).In FACE analyzes, glycoconjugate used at N-connect the inscribe H of glycan or N-dextranase (PNGaseF) or from peptide, discharge at the hydrazine that Ser/Thr connects glycan.The mode that this glycan is distinguished with non-structure with fluorogen is carried out mark in reduction end then.Then with the glycan of fluorogen mark based on lotus/matter of sugar than and hydrodynamics volume and on polyacrylamide gel, separating.Under UV light, obtain gel images, and the composition of glycan is to determine by the migration distance of comparing with reference material.Oligosaccharides can check order by analyzing owing to the migration and variation of removing sugar successively with exoglycosidase digestion by this way.

B. reconstruct O-connects the method for glycan

The O-glycosylation is characterised in that with the O-glycosides key has adhered to various monose to hydroxy-amino-acid.The O-glycosylation is posttranslational modification general in animal and plant circle.The structural complexity of the glycan that is connected with protein O-is considerably beyond the glycan of N-connection.The serine or the threonine residues of the peptide of new translation are modified by peptidyl GalNAc transferase in the compartment of the outside substantially in the inboard of Golgi body.O-is not only in glycosylated site by the sequence-specific of glycosyl transferase and determines, and be by the competition between the different substrate sites and and other outer heredity of being responsible for forming the competition mediation between the glycosyl transferase of glycan to regulate (epigenetic regulation) definite.

The glycan that O-is connected is defined as artificially and has 3 zones: core, main chain and outer regions." core " zone that O-connects glycan is near inner most 2 or 3 sugar of the polysaccharide chains of peptide.The main length of forming by the unified polysaccharide chains that extends to form in main chain zone.Outer regions is showed the structural complexity of height.The structural complexity that O-connects glycan starts from core texture.In most of the cases, connecting first saccharide residue that adds in the consistent site of glycan at O-is GalNAc; Yet should also can be GlcNAc, glucose, mannose, galactose or fucose etc. for sugar.Figure 12 is the diagram that some known O-connect enzyme synthetic in glycan core texture and responsible its body.

In mammalian cell, found the core texture that 8 different O-connect at least, all be based on core-α-GalNAc residue.4 core textures describing in Figure 13 are the most general.Core 1 and core 2 are abundant structures in the mammalian cell, and core 3 and core 4 are found in the expression system of more restricted and organ characteristic's property.The summary that O-connects glycan has Montreuil, Structure and Synthesis ofGlycopeptides, Polysaccharides in Medicinal Applications, pp.273-327,1996, Eds.Severian Damitriu, Marcel Dekker, NY, with Schachter and Brockhausen, The Biosynthesis of Branced O-LinkedGlycans, 1989, Society for Experimental Biology, pp.1-26 (Britain).

See that from disclosure of the present invention the glycan structures that it is evident that the glycosylated peptide of O-can be reconstructed with the similar technology with the glycan description that N-is connected.O-glycan and the difference of N-glycan are that they are connected on serine or threonine rather than the asparagine residue.As described about the reconstruct of N-glycan herein, hydrolase can be used for cutting O-and connects undesired sugar moieties on the glycan, and the extra sugar of wanting can add on it then, thus on peptide the O-glycan structures (referring to Figure 12 and 13) of structure customization.

The glycosylated initial step of O-is to adhere to N-acetylgalactosamine (GalNAc) with any one of at least 11 known α-N-acetylgalactosamine transferase families in the mammalian cell, and each of this enzyme all has strict acceptor peptide specific.Usually, form at least 10 amino acid whose sequences by the acceptor peptide of each enzyme identification.If in the cell of expressing this enzyme, express and they are when roughly being positioned on the Golgi body that UDP-GalNAc also exists then to become O-glycosylated if contain by the peptide of the amino acid sequence of a specific GalNAc-transferase identification.

Yet under the situation of recombinant protein, initial the adhering to of GalNAc may not can take place.Natural α-N-the acetylgalactosamine transferase of express cell can have and the different concensus sequence specificity of expressing of recombinant peptide.

The recombinant peptide of wanting can cannot not be expressed in syntheticly in the bacterial cell of polysaccharide chains, in Escherichia coli.In these cases, partly be favourable at the initial GalNAc of external interpolation.In case recombinant peptide reclaims with the form of solubility, then the GalNAc part can contact when UDP-GalNAc exists and be incorporated on the peptide external with suitable GalNAc transferase by making peptide.

In one embodiment, can have extra amino acid sequence, this amino acid sequence is formed the effective acceptor that is used to shift the sugar that O-connects.This amino acid sequence is by the dna sequence encoding that merges with the coded sequence of peptide in frame, perhaps selectively can be introduced by chemical method.This peptide may lack polysaccharide chains in addition.Selectively, this peptide may have the polysaccharide chains of N-and/or O-connection, but needs extra glycosylation site, as when needing extra glycan substituting group.

In an exemplary embodiment, add amino acid sequence PTTTK-COOH as merging mark, this amino acid sequence is the natural GalNAc receptor sequence among people's mucoprotein MUC-1.Make fused protein at expression in escherichia coli and purifying then.This peptide when existing, UDP-GalNAc is contacted so that the GalNAc residue is transferred in the peptide external with the people GalNAc-transferase T3 or the T6 of reorganization then.

The method that polysaccharide chains on the peptide can further be described with the glycan that connects for N-herein or O-connects is then extended.Selectively, the reaction of GalNAc transferase can be carried out when UDP-GalNAc exists, and the PEG covalency has replaced O-3,4 or 6 positions or N-2 position on UDP-GalNAc.Sugar is conjugated in other places and has a detailed description.Any antigenicity of introducing by new peptide sequence can be easily by the PEGization of relevant glycan is covered.The acceptor site integration technology can be used for not only introducing peg moiety, and introduce other glycan and non-glycan part, including, but not limited to the chelating agent of toxin, anti-infectious agent, cytotoxic agent, radioactive nucleus thuja acid with have the glycan of other functions such as tissue guide.

Conventional immunotoxin contains the MAb chemically conjugated with toxin, and this toxin has been carried out sudden change or chemical modification so that minimize with Normocellular the combination.Example comprises the anti--ricin of B4-blocking-up and the deglycosylated ricin A of the RFB4-chain of guiding CD22 of guiding CD5.The recombinant immunotoxin of latest developments is chimeric proteins, and this chimeric protein is made up of the variable region that is fused to the antibody of the TRA on the archon with recombinant DNA technology.This toxin also often carries out gene engineering and modifies with the binding site of removing normal structure but keep its cytotoxicity.A large amount of differentiation antigens, the acceptor of overexpression or cancer specific antigen have been accredited as the target of immunotoxin, as CD19, CD22, CD20, IL-2 acceptor (CD25), CD33, IL-4 acceptor, EGF acceptor and mutant, Er β 2, Lewis sugar, mesothelin, transferrin receptor, GM-CSF acceptor, Ras, Bcr-Abl and c-Kit, to be used for the treatment of various malignant tumours, comprise hematopoietic cancer, glioma and breast, colon, uterus, bladder and human primary gastrointestinal cancers.Referring to as people such as Brinkmann, Expert Opin.Biol.Ther.1:693-702 (2001); Perentesis and Sievers, Hematology/Oncology Clinics ofNorth America 15:677-701 (2001).

To be used as the method, particularly hematopoietic cell malignant tumour of another kind of treatment human malignancies with the MAb that radioisotope is puted together, this method has high-caliber specificity and effectiveness.The most frequently used isotope that is used for the treatment of is high-octane emitting substance, as ¹³¹I and ⁹⁰Y.Recently, ²¹³Anti--CD33 humanization the MAb of Bi mark also checks in I phase people clinical trial.People such as Reff see above.

Many MAb are used for the treatment of purpose.For example, the reorganization inosculating antibody-CD20MAb that is used for the treatment of some hematopoietic cell malignant tumour is rituximab (Rituxan ^TM) application obtained the approval of FDA in 1997.Other MAb that got permission to be used for the treatment of human cancer from that time comprise: a kind of humanized rat anti-CD 52 antibody alemtuzumab (Campath-1H ^TM); MAb gemtuzumabozogamicin (the Mylotarg of the humanization mouse anti CD33 that puts together with a kind of Calicheamicin ^TM).At present FDA also checked several other be used for safety and the effect that locus specificity send the MAb of delivery cell toxic agents or radiation purpose, as radiolabeled Zevalin ^TMAnd Bexxar ^TMPeople such as Reff see above.

Second important consideration is the accessibility of destination organization to therapeutic agent in the design drug delivery system.This is a situation about will consider especially in the disease of treatment central nervous system (CNS), because blood brain barrier has prevented macromolecular diffusion.Develop several method to get around blood brain barrier and therapeutic agent sent effectively and be delivered to CNS.

Understanding to the iron transfer mechanism from blood plasma to the brain provides the useful tool that gets around blood brain barrier (BBB).The iron of being transported in blood plasma by transferrin is the basis of nearly all cell type.Brain needs iron to carry out metabolic process and to accept iron by the transferrin receptor that is positioned on the brain capillary endothelial cells through receptor-mediated transcytosis and endocytosis.Moos and Morgan, Cellular and Molecular Neurobiology 20:77-95 (2000).Established effectively peptide, protein and liposome are sent be delivered in the brain based on the interactional delivery system that send of transferrin-transferrin receptor.For example, the MAb coupling that can make peptide and anti-transferrin receptor is to obtain bigger brain capture, and Moos and Morgan see above.Similarly, when with the MAb coupling of anti-transferrin receptor, the transhipment that Basic Fibroblast Growth Factor (bFGF) strides across blood brain barrier has obtained enhancing.People such as Song, The Journal ofPharmacology and Experimental Therapeutics 301:605-610 (2002); People such as Wu, Journal of Drug Targeting 10:239-245 (2002).In addition, reported that the liposome that effectively the chemotherapeutics adriamycin is transported in the C6 glioma send delivery system, wherein is attached to transferrin the far-end on the liposome PEG chain.People such as Eavarone, J.Biomed.Mater.Res.51:10-14 (2000).Many United States Patent (USP)s also relate to based on the interactional method of passing of sending that gets around blood brain barrier of transferrin-transferrin receptor.Referring to as U.S. Patent No. 5,154,924,5,182,107,5,527,527,5,833,988,6,015,555.

For the pharmaceutical agent that gets around blood brain barrier other suitable conjugate gametophytes are arranged.For example, U.S. Patent No. 5,672,683,5,977,307 and WO 95/02421 relate to and neurologic agent reagent is striden across blood brain barrier send the method for passing, wherein this reagent is to give with the form with the fusion of part, this part can with the capillary endothelial cells receptor response of brain; WO99/00150 has described a kind of drug delivery system, and the transhipment that its Chinese traditional medicine strides across blood brain barrier is to put together by the MAb with anti-actrapid monotard's acceptor to promote; WO 89/10134 has described chimeric protein, and this chimeric protein comprises peptide that can stride across blood brain barrier with high relatively speed and the hydrophilic neuropeptide that can not carry out transcytosis, thereby as a kind of hydrophilic neuropeptide is incorporated into method in the brain; WO 01/60411 provides a kind of pharmaceutical composition that can easily active constituents of medicine be transported in the brain.This active component is attached on the hibernation specific protein as conjugate, and gives with thyroid hormone or the material that promotes thyroid hormone to produce.In addition, probe into the selectable medicine that is used to get around blood brain barrier and sent the approach of passing.For example, giving in the nose of the therapeutic agent that need not to put together to show is the promising selectable method of passing (Frey, 2002, Drug Delivery Technology, 2 (5): 46-49) sent.

Except that promoting that medicine strides across the transhipment of blood brain barrier, transferrin-transferrin receptor interaction also can be used for the specificity guiding of some tumour cell, and this is because many tumour cells show the overexpression transferrin at it.This strategy has been used for by the transferrin conjugate bioactive macromolecule being sent to be passed into K562 cell (people such as Wellhoner, The Journal ofBiological Chemistry 266:4309-4314 (1991)), and be used for insulin being sent and pass into class enterocyte (enterocyte-like) Caco-2 cell (Shah and Shen, Journal of Pharmaceutical Sciences 85:1306-1311 (1996)) by the transferrin conjugate.

In addition, because function and expression pattern thereof to iron transfer protein have had more understanding, as lactotransferrin acceptor, melanoma transferrin, ceruloplasmin and divalent cation transporter albumen, found that protein (as the melanoma transferrin) that some participate in the iron transfer mechanism or its fragment stride across in the blood brain barrier transhipment or the specific tissue that leads at auxiliary therapeutical agent and have similar efficient (WO 02/13843 A2, WO 02/13873 A2).Send the transferrin that participates in the iron picked-up in passing and related protein summary for medicine as the application of conjugate, referring to Li and Qian, Medical Research Reviews 22:225-250 (2002).

The tissue specificity of therapeutic agent send the notion of passing not to be confined to interaction between transferrin and transferrin receptor or its related protein.For example, described the specific delivery system that send of bone, wherein protein is to put together to improve protein with the amino diphosphonic acid of close bone to pass to sending of mineralized tissue.Uludag and Yang, Biotechnol.Prog.18:604-611 (2002).About the summary of this theme, referring to people such as Vyas, Critical Reviews inTherapeutic Drug Carrier System 18:1-76 (2001).

The purifying of sugar, nucleotide sugar and derivative

Nucleotide sugar that is produced by said method and derivative can be not purified and use.Yet, preferably reclaim product usually.But the well-known technology that is used to reclaim glycosylated sugar of application standard is as thin layer or thick-layer chromatography, column chromatography, ion-exchange chromatography or membrane filtration.Applying membrane filtering preferably is more preferably for being used for reverse osmotic membrane or one or more column chromatography technologies to reclaim, as hereinafter and discuss in the list of references of quoting herein.For example, available membrane filtration removes molecular weight less than 10, and the protein of the reagent of 000Da, this film have about 3000～about 10,000 weight shutoff point.Membrane filtration or inverse osmosis can be used for removing salt and/or purified product sugar (referring to as WO 98/15581) then.The Nanofilter film be a class can make monovalent salt through and keep the salt of multivalence and greater than the reverse osmotic membrane of uncharged solute of about 100～about 2,000 dalton (depending on used film).Thereby in general application, the sugar that is prepared by method of the present invention will be retained on the film, and impurity salt will pass through film.

G. crosslinked group

The preparation of sugar that is used for the modification of method of the present invention comprises modification group adhering to and form stable adduct on saccharide residue, and this adduct is the substrate of glycosyl transferase.Thereby, often preferably use crosslinking agent modification group and sugar are puted together.Can be used for the exemplary dual-function compound that modification group is attached on the sugar moieties is included, but are not limited to difunctional poly-(ethylene glycol), polyamide, polyethers, polyester etc.Making carbohydrate is known with the conventional method that is connected on other molecules in the literature.Referring to as people such as Lee, Biochemistry 28:1856 (1989); People such as Bhatia, Anal.Biochem.178:408 (1989); People such as Janda, people such as J.Am.Chem.Soc.112:8886 (1990) and Bednarski, WO92/18135.In discussion subsequently, the sugar moieties reactive group of the sugar of new life's modification is carried out gentleness handle.The emphasis of this discussion is in order to illustrate purpose clearly.It should be appreciated by those skilled in the art that this discussion also is applicable to the reactive group on the modification group.

Exemplary strategy comprises and will be integrated in the sugar with the sulfydryl of isodigeranyl functional cross-link agent SPDP (positive succinimide-3-(2-pyridine radicals two sulfo-s) propionic acid) protection, then to sulfydryl go to protect with modification group on other sulfydryls form disulfide bond.

If SPDP influences the ability of the sugar of modification as the glycosyl transferase substrate nocuously, certain other crosslinking agent can be used to form disulfide bond so, as 2-imido grpup thiophane or N-succinimide S-acetyl group thioacetic acid (SATA).2-imido grpup thiophane can with primary amine reaction, existing side by side is about to unprotected sulfydryl and is integrated on the molecule that contains amine.SATA also with primary amine reaction, but integrate the sulfydryl of protection, the sulfydryl of this protection is deacetylated to produce free sulfydryl with azanol subsequently.Under each situation, the sulfydryl of integration can freely react to form required disulfide bond with other the sulfydryl or the sulfydryl such as the SPDP of protection.

Above-mentioned strategy is exemplary for being used for connector of the present invention, rather than restrictive.Other crosslinking agents that can be used for modification group and peptide are carried out in the crosslinked Different Strategies are available.For example; TPCH (S-(2-sulfo-pyridine radicals)-L-cysteine hydrazides and TPMPH ((S-(2-sulfo-pyridine radicals) sulfydryl-propiono hydrazides) with in advance with the gentle sugar moieties reaction of handling oxidation of periodates, thereby between the aldehyde that the hydrazides part and the periodates of crosslinking agent generates, form the hydrazone key.TPCH and TPMPH have introduced the sulfydryl group of 2-pyridine radicals thioketones protection on sugar, this group can go protection also to be used to subsequently put together with DTT, as form disulfide bond between composition.

If finding disulfide bond is unsuitable for the sugar that produces stable modification, can be applicable to other crosslinking agents of the more stable key of integration between the composition so.Isodigeranyl functional cross-link agent GMBS (N-gama-malimidobutyryloxy) succinimide) and SMCC (succinimido 4-(N-maleimide-methyl) cyclohexane) and primary amine reaction, thus maleimide base group is incorporated on the composition.This maleimide base group subsequently can with the sulfydryl reaction that can introduce by previously described crosslinking agent on other compositions, thereby between composition, form stable thioether bond.If the sterically hindered sugar that has disturbed the active of composition or modified between the composition is as the ability of glycosyl transferase substrate, can use the crosslinking agent that between composition, to introduce than long spacer arm so, and this crosslinking agent comprises the derivative of some previously described crosslinking agents (being SPDP).Thereby, there are a large amount of useful suitable crosslinking agents; They each all is to depend on its effect that sugar of the suitableeest peptide conjugate and modification is produced to select.

Many reagent can be used for modifying composition with sugar of the modification of chemical crosslinking in the molecule (for the summary of crosslinking agent and crosslinked program, referring to Wold, F., Meth.Enzymol.25:623-651,1972; Weetall, H.H. and Cooney, D.A., Enzymes as Drugs (Holcenberg and Roberts, eds.) pp.395-442, Wiley, New York, 1981; Ji., T.H., Meth .Enzymol.91:580-609,1983; People such as Mattson, Mol.Biol.Rep.17:167-183,1993, all be incorporated herein by reference herein).Preferred cross-linking agents can be derived from various distance of zero mark degree, with crosslinking agent bifunctional and the isodigeranyl function.The crosslinking agent of distance of zero mark degree comprises directly puting together of two inner chemical groups, and does not introduce outside material.The reagent that the catalysis disulfide bond forms belongs to this type.Another example is to induce the condensation of carboxyl and primary amino radical group and the reagent that forms amido link, as carbodiimide, ethyl carbonochloridic acid, Woodward reagent K (2-ethyl-5-phenylisoxazolium-3 '-sulfonate) and carbonyl dimidazoles.Except that these chemical reagent, TGase (glutamy-peptide gamma glutamyltransferase; EC 2.3.2.13) can be used as the crosslinking agent of distance of zero mark degree.The acyl group transfer reaction of the carbamyl of the glutamine residue that this enzymatic protein connects is rolled into a ball as substrate with primary amino radical usually.Together preferred-as to contain two identical or different sites respectively with different-bifunctional reagent, this site is reactive for amino, sulfydryl, guanidine radicals, indoles or unspecific group.

2. preferred specificity site on the crosslinking agent

A. amino-reactive group

In a preferred embodiment, the site on the crosslinking agent is the amino-reactive group.The useful non-limitative example of amino-reactive group comprises N-hydroxy-succinamide (NHS) ester, polyurethane, isocyanates, acyl halide, aryl nitride, p-nitrophenyl ester, aldehyde and sulfonic acid chloride.

The NHS ester preferably with primary (comprising aromatics) amine groups reaction of the sugared composition of modifying.The imidazole group of histidine known can with the primary amine competitive reaction, but its product is unstable and is easy to hydrolysis.This reaction comprises the nucleophillic attack of amine on the acid carboxyl of NHS ester forming acid amides, thereby discharges N-hydroxy-succinamide.Thereby the positive charge of initial amino group has then been lost.

Polyurethane is the most specific acylating reagent that reacts with the amine groups of the sugared composition of modifying.When 7～10 pH, polyurethane only with primary amine reaction.The imines ester is attacked to produce intermediate in primary amine nucleophilic ground, and this intermediate is decomposed into amidine and is decomposed into new imidoether when hanging down pH when high pH.This new imidoether can with another primary amine reaction, thereby make two amino groups crosslinked, this is the situation that single function imidoether of inferring carries out difunctional reaction.With the primary product of primary amine reaction be amidine, this amidine is the alkali stronger than initial amine alkalescence.Positive charge on the therefore initial amino group has then kept.

The primary amine reaction of the sugared composition of isocyanates (and isothiocyanates) and modification is to form stable key.They produce relative unsettled product with the reaction of sulfydryl, imidazoles and tyrosyl group.

Also as amino specific reagent, wherein the nucleophilic amine of affine composition is attacked acid carboxylic group to the acyl group nitride under the condition of alkalescence such as pH8.5.

Aryl halide is as 1, and 5-two fluoro-2,4-dinitro benzene preferably react with the amino group of the sugared composition of modifying and the phenolic group group of tyrosine, but also react with sulfydryl and imidazole group.

Single-and the p-nitrophenyl ester of dicarboxylic acids also be useful amino-reactive group.Although the specificity of this reagent is not high especially, α-and the reaction of epsilon-amino group be the fastest.

The primary amine reaction of the sugar of aldehyde such as glutaraldehyde and modification.Although in the reaction of amino group and aldehyde, formed unsettled schiff bases, the sugar that the enough stable crosslinked modifications of glutaraldehyde energy are modified.When typical crosslinked pH condition pH6-8, annular polymeric is dewatered to form the undersaturated aldehyde polymer of alpha-beta.Yet schiff bases is stable when puting together with another pair key.The Resonant Interaction of two two keys has stoped the hydrolysis of Schiff key.In addition, the amine of high local concentrations can be attacked ethylene double bond to form stable Michael addition compound product.

The a plurality of sites reaction of the sugared composition of aromatics sulfonic acid chloride and modification, but with the reaction of amino group be most important, the result forms stable sulfonamides key.

B. sulfydryl reactive group

In another preferred embodiment, this site is the sulfydryl reactive group.Useful nonrestrictive sulfydryl reactive group comprises maleimide, alkyl halide, pyridyl disulfide and sulfo-phthalimide.

The sulfydryl radical reaction of the sugared composition of maleimide and modification is to form stable thioether bond.They also react with the imidazole group of low-down speed and primary amino radical group and histidine.Yet, can think that when pH7 maleimide is the specific group of sulfydryl, this is because the reaction rate of simple mercaptan is higher 1000 times than the reaction rate of corresponding amine when pH7.

Alkyl halide and sulfydryl, sulphide, imidazoles and amino group reaction.Yet when the subalkaline pH, alkyl halide is main to react to form stable thioether bond with sulfydryl in neutrality.When higher pH, with the reaction of amino group be dominant.

Pyridyl disulfide reacts the disulphide that mixes to form with the free sulfhydryl base by disulfide exchange.Pyridyl disulfide is the most specific sulfydryl reactive group as a result.

Sulfo-phthalimide and free sulfhydryl base radical reaction are to form disulphide.

C. carboxyl-reactive residue

In another embodiment, will in water and organic solvent, be used as carboxyl-reactive reagent by soluble carbodiimide.These compounds and free carboxy radical reaction to be to form pseudo-urea, then this pseudo-urea can with available amine coupling to form amido link.The program of modifying carboxylic group with carbodiimide is (referring to people such as Yamada, Biochemistry 20:4836-4842,1981) well known in the art.

3. preferred non-specific site in the crosslinking agent

Except that practical site specific reaction part, the present invention also relates to use nonspecific reactive group so that sugar is connected with modification group.

Exemplary non-specific crosslinking agent comprises in the dark the photoactivation type group of inertia fully, and this group can change reactive kind into after the photon that absorbs suitable energy.In a preferred embodiment, the photoactivation type group is selected from the nitrene precursor that generates by heating or photodissociation nitride.Electronic defects type nitrene is extremely reactive, and can with various chemical bonding reactions, comprise N-H, O-H, C-H and C=C.Although can use 3 class nitride (aryl, alkyl and acyl derivative), the aryl nitride is preferred at present.The aryl nitride after photodissociation with good than with C-H of the reactivity of N-H and O-H.Electronic defects type aryl nitrene carries out ring extension apace to form the dehydrogenation azepine, and this dehydrogenation azepine tends to and the reaction of nucleophilic thing, rather than forms C-H insertion product.The reactivity of aryl nitride can strengthen by have electron-withdrawing substituent such as nitro or oh group in ring.This substituting group is shifted the absorption maximum of aryl nitride onto bigger wavelength.Unsubstituted aryl nitride has absorption maximum in the scope of 260-280nm, and hydroxyl and nitro aryl nitride significantly absorb the light that surpasses 305nm.Therefore, hydroxyl and nitro aryl nitride are most preferred, and this is because they make it possible to use the photodissociation condition lower to affine composition harm than unsubstituted aryl nitride.

A. generate or eliminate the glycosylation site that N-connects

The present invention relates to use following peptide, wherein the changing with respect to native peptides of the polysaccharide chains site on this peptide.Usually, the polysaccharide chains that N-connects is that to be connected to the one-level peptide at asparagine residue structural, and wherein be arranged in can be by the amino acid sequence of the film on the endoplasmic reticulum (ER) in conjunction with glycosyl transferase identification for this asparagine residue.Usually, the structural recognition site of one-level peptide is sequence asparagine-X-serine/threonine, and wherein X can be any amino acid except that proline and aspartic acid.Although this recognition site is typical, the present invention further is included in other recognition sites and has the peptide that N-connects glycan, and wherein the chain of this N-connection is to add with glycosyl transferase natural or that recombinate.

Because the glycosylated recognition site that N-connects is known, so generating the one-level peptide sequence of sudden change is within those skilled in the art's technical scope, wherein in the sequence of described sudden change, remove natural N-and connected the glycosylation recognition site, perhaps selectively generated one or more extra N-glycosylation recognition sites in addition again.The most simply, asparagine residue can be removed from the primary sequence of peptide, thus the attachment site of removal glycan, thereby can from mature peptide, remove a kind of glycan.For example, available gene engineering method will have AsparagineThe natural site of identification of-serine-serine sequence is processed as to have Leucine-serine-serine sequence, thus the glycosylation site that N-connects eliminated in this position.

Further, the glycosylation site that N-connects can be removed by the residue that changes in the recognition site, thereby even there is asparagine residue, one or more other identification residues but do not exist.For example, can make native sequences asparagine-serine- SerineSport asparagine-serine- LysineThereby, eliminate the N-glycosylation site in this position.The glycosylation site that connects at N-comprises under the situation of the residue except that above-mentioned typical recognition site, the technical staff can determine that suitable glycosyl transferase discerns necessary sequence and residue, at least one residue that suddenlys change then, thus suitable glycosyl transferase is no longer discerned this site.In other words, handling to generate or to remove or generate and remove glycosylation site simultaneously to the primary sequence of peptide is in technical staff's technical scope, thereby can generate the peptide of the glycosylation pattern with change.Therefore, any one-level peptide sequence that the present invention should be interpreted as being confined to provide herein is as unique sequence of carrying out glycan reconstruct, and should be interpreted as comprising any or all of peptide sequence that is suitable for carrying out glycan reconstruct.

In order to generate the peptide of sudden change, the nucleotide sequence of encoded peptide primary sequence is changed, thereby the natural codon mutation that makes coding natural amino acid residue is to generate the codon of other amino acid residues of coding.The technology that changes nucleotide sequence is general in this area, and is described in for example any well-known molecular biology manual.

In addition, the available standards technology is at the nucleic acid of external composite coding one-level peptide structure.For example, available rules synthetic nucleic acid molecule in " gene machine " as the phosphoramidite method.If need the double-stranded DNA of chemosynthesis in the application as nucleic acid or its fragment, each complementary strand can synthesize separately so.The production of short nucleic acid (60～80 base-pairs) is simple technically, and can its annealing be realized by synthetic complementary strand.For the production of long nucleic acid (＞300 base-pairs), need specific technology, this is because the coupling efficiency in each synthetic circulation of chemical dna seldom is 100%.In order to address this problem, synthetic gene (double-stranded) is to be that the single-chain fragment assembling of 20～100 nucleotide comes with the pattern of module from length.For the synthetic summary of polynucleotides, referring to as Glick and Paternak (Molecular Biotechnology, Principles and Applications ofRecombinant DNA, 1994, ASM Press), people such as Itakura (1984, Annu.Rev.Biochem.53:323) and people (1990, Proc.Nat ' l.Acad.Sci.USA 87:633) such as Climie.

In addition, the change in the nucleotide sequence of encoded peptide can form by direct mutagenesis.As is understood, this technology is generally used the phage vector that exists with strand and double chain form simultaneously.The general carrier that is used for direct mutagenesis comprises the carrier as the M13 phage.These phages are easy to obtain, and it is used, and normally those skilled in the art is well-known.Also use double-stranded plasmid in direct mutagenesis routinely, this has eliminated target nucleic acid has been transferred to step the phage from plasmid.

Usually, direct mutagenesis is to be undertaken by two chains that at first obtain single-stranded vector or fuse double-stranded carrier, wherein should the two strands carrier comprises the dna sequence dna of the peptide that coding is wanted in its sequence.The normally synthetic preparation of Oligonucleolide primers with mutant nucleotide sequence of wanting.Make the annealing of this primer and single-stranded vector then, handle to finish synthesizing of chain with sudden change with the Klenow fragment of archaeal dna polymerase such as Escherichia coli polymerase I then.Thereby, formed the isodigeranyl serobila, the sequence of the initial nothing sudden change of chain encoding wherein, and another chain has the sudden change of wanting.Then this isodigeranyl serobila is used to transform or cell that transfection is suitable,, and selects to comprise the clone of the recombinant vector of sequence with sudden change as Bacillus coli cells.People such as Kunkel (1987, people such as Kunkel, Methods Enzymol.154:367-382) have designed a kind of hereditary selection scheme has been integrated the oligonucleotides of mutagenesis with enrichment clone.Selectively, can be with the commercial heat endurance enzyme of buying such as Taq polymerase and PCR ^TMBe used for the Oligonucleolide primers of mutagenesis is integrated into the dna fragmentation of amplification, this fragment cloning can be gone among the suitable clone or expression vector then.People such as Tomic (1990, Nucl.Acids Res., 12:1656) and people such as Upender (1995, Biotechniques, PCR 18:29-31) ^TM-mediated mutagenesis method provides two examples of this rules.Except that the heat endurance polymerase, also use the PCR of heat endurance ligase ^TMAlso can be used for the mutagenic oligonucleotide of phosphorylation is integrated in the dna fragmentation of amplification, this fragment cloning can be gone among the suitable clone or expression vector then.An example of this rules is provided by the method for mutagenesis of Michael (1994, Biotechniques 16:410-412) description.

Not every Asn-X-Ser/Thr sequence all is that N-is glycosylated, and this points out the residing front and back of this primitive environment is important.In another method, generated and had library that new N-connects consistent site mutation peptide to identify new N-connection site, this new N-connection site is carried out glycosylation in vivo, and is useful to activity, stability or other features of peptide.

As previously noted, the concensus sequence that adds the polysaccharide chains of N-connection in glycoprotein is Asn-X-Ser/Thr, and wherein X can be any amino acid.Coding can suddenly change with coding Ser and/or Thr with the known standard method of those skilled in the art apart from the amino acid whose nucleotide sequence of two positions of carboxyl terminal one side of Asn.Stated that as mentioned not every Asn-X-Ser/Thr site is all modified by adding glycan.Therefore, must make the glycoprotein of each recombination mutation in fungi, yeast or animal or mammalian expression systems, express and analyze the interpolation of the polysaccharide chains that N-connects.The technology that characterizes glycosylation site is that those skilled in the art is well-known.Further, the biological function of the recombinant glycoprotein of sudden change can be determined with the determination method that for the specified protein of checking is standard.Thereby, the primary sequence of peptide is handled and identified the new glycosylation site that contains therein, and determine that further this novel site then becomes simple thing to the effect of the biologic activity of peptide.

In a selectable embodiment, coding is that the amino acid whose nucleotide sequence of two positions can suddenly change with coding Asn with the known standardization program of those skilled in the art apart from amino terminal one side of Ser and/or Thr.Determined whether to generate new glycosylation site and this site is as indicated above to the method for the effect of the biologic activity of peptide.

B. generate or eliminate the glycosylation site that O-connects

Adding the glycosylation site of O-connection in peptide can realize by the one-level amino acid sequence that changes peptide easily, contains the glycosylation site that one or more extra O-are connected thereby its peptide one-level amino acid sequence with beginning is compared.In peptide, add the glycosylation site that O-connects also can comprise-realize in the peptide of OH group (being preferably serine or threonine residues), thereby the OH group is come-at-able and can be used in the glycosylation that O-connects by one or more amino acid kinds are integrated in its peptide sequence.The change of the glycosylation site that is connected with N-in the peptide is similar, and the one-level amino acid sequence of peptide preferably changes on nucleotide level.Specific nucleotide changes in can the dna sequence dna to encoded peptide, thus the amino acid that this sequential coding is wanted.Sudden change among the DNA preferably realizes with method as known in the art, as the above-mentioned phosphoramidite DNA synthetic method and the technology of direct mutagenesis.

Selectively, the coding nucleotide sequence of inferring the site that is used for adding the glycan that O-connects can add this molecule at 5 ' or 3 ' end of dna molecular with one or several copy.Whether can make the dna sequence dna of change express and analyze the sequence of adding and this sequence then in fungi, yeast or animal or mammalian expression systems in peptide is the glycosylation site that has the O-of function to connect.In brief, He Cheng peptide receptor sequence is 5 ' or 3 ' the terminal introducing at nucleic acid molecule.In principle, the interpolation of such sequence is less to the destructiveness of the glycoprotein of gained as a result when expressing in suitable expression system.The DNA of change is expressed in Chinese hamster ovary celI or other suitable expression systems, and check the glycosylation site of expressed protein to determine whether to exist O-to connect therein.In addition, the existence that can determine polysaccharide chains whether.

In the another one method, the favourable site of new O-connection site can be found in the library of containing the peptide of various new O-connection site by generation in peptide.For example, the consistent amino acid sequence by N-acetylgalactosamine transferase interpolation N-acetylgalactosamine depends on used specific transferase.Can scan the amino acid sequence of peptide to identify continuous amino acid group, this amino acid group can be suddenlyd change to generate the potential site of the polysaccharide chains of adding the O-connection.The available standardization program that well known to a person skilled in the art as previously described of these sudden changes generates.For the glycosylation site that determines whether any discovery is actually glycosylated, make the peptide of each recombination mutation in suitable expression system, express and the existence of the interpolation in subsequent analysis site and/or the polysaccharide chains that O-connects whether.

C. the chemosynthesis of peptide

Can the suddenly change undesired character of the biologic activity wanted with enhancing or function, minimizing peptide and/or add new activity or function of the peptide that is used for the inventive method to peptide." reasonably peptide design " can be used for generating the peptide of this change.In case the amino acid sequence of peptide and structure are known and have planned the sudden change wanted, but most convenient ground suddenlys change at the corresponding nucleic acids codon so, this nucleic acid codon coding is wanted the amino acid residue that suddenlys change.Those skilled in the art is easy to determine how nucleotide sequence is changed based on the knowledge of the codon-bias of general genetic code and selected expression system.The amino acid residue that can in codon, suddenly change and polymerization be gone in the peptide to change in translation process.Selectively, can suddenly change, thereby the amino acid residue of corresponding encoded is constant, but the selection of codon is more suitable in the peptide expression systems of wanting codon.For example, available other amino acid replacement cys-residue to be removing the disulfide bond in the native peptides, can suddenly change changing biologic activity to the catalytic domain, and can process the isotype of peptide usually.This sudden change can be point mutation, disappearance, insertion and brachymemma etc.

The technology that makes amino acid mutation specific in the peptide is well known in the art.Above-mentioned side-directed mutagenesis is highly suitable for the orthomutation of codon.Oligonucleotide mediated method of mutagenesis also goes through in people such as Sambrook (2001, Molecular Cloning:A Laboratory Manual, Cold Spring Harbor Laboratory, New York is since 15.51 pages).Can insert mutagenesis, nuclease Bal31 digestion and linker scanning mutagenesis and other methods well known in the art are carried out systematic disappearance, insertion and brachymemma (people such as Sambrook with joint, 2001, Molecular Cloning:A Laboratory Manual, Cold Spring Harbor Laboratory, New York).

The peptide design of reasoning (rational) has been successfully used to increase the stability of enzyme to heat inactivation and oxidation.For example, the stability of enzyme can be by removing asparagine residue in the α-Dian Fenmei (people such as Declerck, 2000, J.Mol.Biol.301:1041-1057), to α-Dian Fenmei (people such as Igarashi, 1999, Biosci.Biotechnol.Biochem.63:1535-1540) and introduce the structural detail of rigidity more such as proline in the D-xylose isomerase (people such as Zhu, 1999, Peptide Eng.12:635-638) and improve.Further, the introducing of extra hydrophobic contact can be stablized 3-Isopropylmalate dehydrogenase (people such as Akanuma, 1999, Eur.J.Biochem.260:499-504) hydrogenlyase that obtains and from pseudomonad species (Pseudonomas sp.) (people such as Rojkova, 1999, FEBSLett.445:183-188).The mechanism of the stabilization of these sudden changes can be applicable to many peptides usually.Expect that these and the peptide that similarly suddenlys change for reconstruct in the method for the present invention are useful.

2. random mutagenesis technology

The new peptide that is used for method of the present invention can be used on the technology of introducing random mutation in the coded sequence of nucleic acid and generates.Nucleic acid is expressed in the expression system of wanting, and to the peptide purpose of appraisals character of gained as a result.The technology of random mutation being introduced dna sequence dna is well known in the art, and comprises PCR mutagenesis, saturation mutagenesis and degenerate oligonucleotide method.Referring to Sambrook and Russell (2001, Molecular Cloning, A Laboratory Manual, Cold Spring Harbor Press, Cold Spring Harbor, NY) and people such as Ausubel (2002, Current Protocols in Molecular Biology, John Wiley﹠amp; Sons, NY).

In PCR mutagenesis, with the fidelity of the Taq polymerase that reduces be used for to clone's dna fragmentation introduce random mutation (people such as Leung, 1989, Technique1:11-15).This is that random mutation is incorporated into very strong and relative method fast in the dna sequence dna.The DNA zone of carrying out mutagenesis is to increase under the condition of the fidelity that reduces Taq archaeal dna polymerase synthetic DNA with polymerase chain reaction (PCR), as the dGTP/dATP ratio of application change with by add Mn in the PCR reaction ²⁺The set of dna fragmentation of amplification is inserted in the suitable cloning vector so that the library of sudden change at random to be provided.

Saturation mutagenesis makes it possible to introduce fast a large amount of single bases and substitutes (people such as Mayers, 1985, Science 229:242) in clone's dna fragmentation.This technology comprises that for example being used in external chemical treatment or radiation to single stranded DNA generates sudden change and synthetic complementary DNA chain.Mutation frequency can be regulated by regulating the fierce degree of handling, and it is alternative to obtain all possible base substantially.Because not relating to the heredity of the fragment of suddenling change, this program selects, so can obtain substituting of neutral alternation and those change functions.The sequential element guarded is not partial in the distribution of point mutation.

The library of nucleic acid homologue also can generate from a cover degenerate oligonucleotide sequence.The chemosynthesis of degenerate oligonucleotide sequence can be carried out on automatic dna synthesizer, and synthetic gene can be connected on the suitable expression then.Degenerate oligonucleotide synthetic be as known in the art (referring to as Narang, SA (1983) Tetrahedron 39:3; People such as Itakura (1981) Recombinant DNA, Proc 3 ^RdCleveland Sympos.Macromolecules, ed.AG Walton, Amsterdam:Elsevierpp.273-289; People (1984) Annu.Rev.Biochem.53:323 such as Itakur a; People such as Itakura (1984) Science 198:1056; People such as Ike (1983) Nucleic Acid Res.11:477).This technology has been applied in the orthogenesis of other peptides (referring to as people such as Scott (1990) Science 249:386-390; People such as Roberts (1992) PNAS 89:2429-2433; People such as Devlin (1990) Science 249:404-406; People such as Cwirla (1990) PNAS 87:6378-6382 and U.S.Pat.No.5,223,409,5,198,346 and 5,096,815).

D. insect

The insect cell that insect cell is particularly cultivated can be expressed the peptide of the glycan structures with N-connection, and the glycan structures that this N-connects is seldom sialylated, and is generally comprised within the mannose residue that has or do not have the extra fucose that adheres on it.Being present in this class glycan structures on the peptide that produces in the insect cell of cultivation and the example of mannose glycan thereof shows in Fig. 6.In this case, can have or not exist the core fucose, if present, this core fucose can be connected to glycan by several different keys.

Shaft-like virus-mediated expression has become particularly suitable (people such as Altmann, 1999, Glycoconjugate J.16:109-123) to the production of recombinant peptide in the insect cell.Aspect the processing, insect cell is only second to mammalian cell after peptide folds and translates.Yet, noticed as mentioned, the N-glycosylation of peptide and the N-glycosylation in the mammalian cell be variant in many aspects in the insect cell, and particularly insect cell often generates the glycan structures of brachymemma, and this glycan structures comprises and only contains 3 or the oligosaccharides of 2 mannose residues only sometimes.These structures can be substituted by fucosyl residues extraly.

According to the present invention, can be at first be reconstructed with generation at the external peptide that produces in to insect cell and have the glycosylated peptide of wanting by selectively remove any alternative fucosyl residues with suitable fucosidase.Peptide comprises under the situation of three basic mannose core textures after removing fucosyl residues, and what all needed so is to have the glycosylated peptide of wanting external with generation to the suitable sugar of three mannose core textures interpolation.Peptide may only contain under the situation of 2 mannose residues in glycan structures after removing any fucosyl residues, available mannose transferase and suitable donor molecule such as GDP-mannose add the 3rd mannose residue, have the glycosylated peptide of wanting with generation thereby add suitable residue.Randomly, also can from these kinds, generate single feeler glycan.

E. plant

Plant cell as the peptide producer provides different situations.Although the N-that produces in the plant connects glycan and comprises three mannose core textures, this pentasaccharides main chain can comprise several different extra sugar as shown in Figure 5.For example, in one case, this three mannoses core texture is to be replaced by the fucosyl residues that the xylose residues of

β

1,2 connection and

α

1,3 connect.In addition, plant cell also can produce the Man5GlcNAc2 structure.The peptide that produces in the plant cell often is high antigenic owing to have

core α

1,3 wood sugar and fucose on glycan structures, and will not remove from blood flow apace owing to there is not terminal sialic acid residues after in being incorporated into mammal.Therefore, these peptides are reconstructed, otherwise it has been generally acknowledged that they are not suitable for as the therapeutic agent in the mammal unless be used in method provided herein.Although find that some monoclone antibodies of expressing in the plant are non-immunogenicities in mouse, but this polysaccharide chains that possible is is non-immunogenicity (people such as Chargelegue owing to be imbedded in the Fc zone of these antibody, 2000, Transgenic Res.9 (3): 187-194).

According to the explanation that provides herein, at present possible is to be created on the peptide that produces in the plant cell, and wherein the glycan structures of the increase number that exists thereon comprises basic three mannose core textures or Man3GlcNAc4 structure.This is by realizing that up to reaching basic three mannose core textures or Man3GlcNAc4 structure this glycosidase comprises fucosidase with the extra sugar of the external excision of being combined in of suitable glycosidase.These cleavage reactions also should comprise from structure removes any fucose or xylose residues to eliminate the antigenicity of final peptide when in the introducing mammal.Has the plant cell that suppresses the sudden change that fucose and xylose residues add to three mannose core textures and is (people such as von Schaewen, 1993, PlantPhysiology 102:1109-1118) as known in the art.The present invention has expected that these cells have application in the peptide of the glycan that lacks fucose and wood sugar in production.After having produced basic three mannose cores or Man3GlcNAc4 structure, extra sugar can be added to then on it to obtain having the glycosylated peptide of wanting, the treatment that therefore this peptide is suitable in the mammal is used.

Many people think that genetically modified plants are the selected expression systems of medicine peptide.Potentially, plant can provide cheap recombinant peptide source.Estimated that the comparable cost of producing identical peptide in Escherichia coli of the production cost of recombinant peptide hangs down 10～50 times in the plant.Use small difference arranged although compare in the plant codon with animal, this can be compensated by regulating recombinant DNA sequence (referring to people such as Kusnadi, 1997, Biotechnol.Bioeng.56:473-484; People such as Khoudi, 1999, Biotechnol.Bioeng.135-143; People such as Hood, 1999, Adv.Exp.Med.Biol.464:127-147).In addition, peptide is synthetic, secretion is very similar in plant and animal with posttranslational modification, and tiny difference (referring to people such as Fischer, 2000, J.Biol.Regul.Homest.Agents 14:83-92) is only arranged in the plant glycosylation.Then, polluted by animal pathogene, microbial toxin and carcinogenic sequence from the product of genetically modified plants is also unlikely.

The expression of recombinant peptide is well known in the art in the plant cell.Except that genetically modified plants, peptide also can the transgenic plant cells culture (people such as Lee, 1997, Mol.Cell.7:783-787) and in the non-transgenic plant with the recombinant plant virus inoculation produce.Published several the books of describing the genetic transformation process of plant cell: Potrykus (1995, Genetransfertoplants, Springer, New York), Nickoloff (1995, Plantcellelectroporation and electrofusionprotocols, Humana Press, Totowa, New York) and Draper (1988, Plantgenetic transformation, Oxford Press, Boston).

Antibody and generation method thereof

As used herein, term " antibody " refers to the immunoglobulin molecules that can be specifically combines with specific antigen decision position on the antigen.Antibody can be the complete immunoglobulin that is derived from natural origin or is derived from recombinant sources, perhaps the immunoreactivity part of complete immunoglobulin.Antibody generally is the immunoglobulin molecules tetramer.Antibody among the present invention can exist with various forms, and this form comprises as polyclonal antibody, monoclone antibody, Fv, Fab and F (ab) ₂And single-chain antibody and humanized antibody (people such as Harlow, 1999, Using Antibodies:ALaboratory Manual, Cold Spring Harbor Laboratory Press, NY; People such as Harlow, 1989, Antibodies:A Laboratory Manual, Cold Spring Harbor, New York; People such as Houston, 1988, Proc.Natl.Acad.Sci.USA 85:5879-5883; People such as Bird, 1988, Science 242:423-426).

As used herein, term " synthetic antibody " refers to the antibody that generates with recombinant DNA technology, as by the antibody of described phage expression herein.This term also should be interpreted as the antibody that the amino acid sequence by the DNA of composite coding and expressing antibodies or encoding antibody generates, and wherein DNA or amino acid sequence are to obtain with available in this area and well-known synthetic DNA or amino acid sequence technology.

Monoclone antibody at full-length peptide or fragments of peptides can prepare with any well-known Monoclonal Antibody program, be described in people such as Harlow (1988 as those, Antibodies, ALaboratory Manual, Cold Spring Harbor, NY) and people such as Tuszynski (1988, Blood is in 72:109-115).The also available chemical synthesising technology of the peptide of wanting is synthetic.Selectively, the DNA of the peptide wanted of coding can clone and express from suitable promoter sequence in being suitable for generating the cell of a large amount of peptides.At the monoclone antibody of peptide be with as herein the standardization program of institute's reference from mouse, generate with this peptide immunity inoculation.

Coding is used in the nucleic acid of the monoclone antibody that program described herein obtains and can clones and check order with technology available in this area, and be described in as people such as Wright (1992, Critical Rev.in Immunol.12 (3,4): 125-168) reach in the list of references of quoting therein.Further, antibody of the present invention can (1997, Thrombosis and Hematocyst 77 (4): the technology 755-759) be carried out " humanization " with being described in people's (seeing above) such as Wright and people such as list of references of quoting therein and Gu.

In order to generate phage antibody library, at first from the mRNA of cell (as hybridoma), obtain the cDNA library from separating, this mRNA expresses the peptide of wanting that will be expressed on the phage surface, as the antibody of wanting.The cDNA copy of mRNA produces with reverse transcriptase.The cDNA of coding immunoglobulin fragment obtains by PCR, and the dna clone of gained is as a result gone in the suitable phage vector to generate the phage DNA library, and this library comprises the immunoglobulin gene that DNA limits.The program of phage library that preparation comprises allogeneic dna sequence DNA is well known in the art, and be described in as Sambrook and Russell (2001, Molecular Cloning:A LaboratoryManual, Cold Spring Harbor, NY).

The phage of the antibody that can want coding is processed, thereby peptide shows in its surface that in such a way promptly these peptides can its corresponding binding peptide combination, as antibody at antigen.Therefore, when the phage of expressing specific antibodies carries out incubation when the cell of expressing corresponding antigens exists, phage will be attached on the cell.The phage of expressing antibodies will not be not joined on the cell.This panning technique is well known in the art and is described in as among the people such as Wright (seeing above).

Developed the method for producing people's antibody with the M13 phage display, as those are described in the above (people such as Burton, 1994, Adv.Immunol.57:191-280).Basically, the cDNA library generates from mRNA, and this mRNA obtains from the cell colony that produces antibody.The immunoglobulin gene that this mRNA coding is reset, thereby the immunoglobulin gene of the same rearrangement of cDNA coding.The cDNA of amplification is cloned in the M13 expression vector, thereby is created on the phage library of its surface expression people antibody fragment.Show the phage of target antibody by antigen in conjunction with selection, and it is bred in bacterium to produce the human immunoglobulin(HIg) of solubility.Thereby synthetic opposite with conventional monoclone antibody, this program makes the DNA of coding human immunoglobulin(HIg) rather than the cell immortalityization of expressing human immunoglobulin.

The reconstruct of antagonist molecule glycan

One class peptide is the specific glycosylation of immunoglobulin has particular importance to the biologic activity of these peptides effect.The present invention should not be construed as the immunoglobulin that only is confined to the IgG class, and should be interpreted as comprising the immunoglobulin of IgA, IgE and IgM antibody-like.

Further, the present invention should not be construed as the conventional antibody structure that only is confined to any kind.On the contrary, the present invention should be interpreted as comprising all types of antibody molecules, comprises as antibody fragment, chimeric antibody, people's antibody, humanized antibody etc.

General immunoglobulin molecules comprises effect part and antigen-binding portion thereof.For the summary of immunoglobulin, referring to people such as Harlow, 1988, Antibodies:A Laboratory Manual, Cold Spring Harbor, New York; With people such as Harlow, 1999, Using Antibodies:A Laboratory Manual, Cold Spring Harbor Laboratory Press, NY.The effect of immunoglobulin partly is positioned at the Fc part and the part of molecule and is responsible for the effective combination of immunoglobulin to its relevant cell receptor.The immunoglobulin molecules particularly incorrect glycosylation in this molecule Fc partial C H2 domain can influence the biologic activity of immunoglobulin.

About Immunoglobulin IgG, more specific is, whether IgG effector function major part contains the decision of N-acetyl-glucosamine (GlcNAc) residue by IgG, and this residue is attached to the 4-0 position of branch's mannose of three mannose cores of the connection of the N-on the asparagine (Asn) 297 glycan in the IgG molecule CH2 domain.This residue is known as " GlcNAc of five equilibrium ".The purpose of adding the GlcNAc of five equilibrium to natural or reorganization IgG molecule or containing in the N-polysaccharide chains of chimeric construct body of IgG-Fc is the Fc immunological effect function optimization that makes this molecule Fc part.This effector function can comprise cytotoxicity (ADCC) and any other the biological action that relies on antibody, and this biological action need be to Fc _γEffective combination of R acceptor and with the combining of the C1 composition of complement.The GlcNAc that has described five equilibrium for the importance of the maximum immunological effect function that realizes the IgG molecule (people such as Lifely, 1995, Glycobiology 5 (8): 813-822; People such as Jeffris, 1990, Biochem.J.268 (3): 529-537).

The glycan of finding at the glycosylation site of the Asn 297 of IgG molecule CH2 domain is structurally for the IgG molecule of finding to be circulated in the humans and animals blood plasma, and the IgG that is produced by the immortalization mammal and the insect cell line of myeloma cell, hybridoma and various transfections is distinctive.In all cases, the N-glycan is (Man3, GlcNAc4, Gal2, NeuAc2, the Fuc1) completely of high mannose chain or the GlcNAc that has or do not have five equilibrium or incomplete pair of variable feeler chain (people such as Raju, 2000, Glycobiology 10 (5): 477-486; People such as Jeffris, 1998, Immunological.Rev.163L59-76; People such as Lerouge, 1998, Plant Mol.Biol.38:41-48; People such as James, 1995, Biotechnology 13:592-596).

These results significantly with those opposite with report in the studying in great detail of ox ST6Gal I, in this research, in 24 hours, be less than 50mU/mg protein can cause be less than 50% sialylated, and 1070mU/mg protein can cause that about 85-90%'s is sialylated.People such as Paulson (1977), J.Biol.Chem.252:2363-2371; People such as Paulson (1978), J.Biol.Chem.253:5617-5624.By another seminar to rat

α

2,3 and the research of α 2, the 6 sialyltransferases complete sialylated enzyme concentration that needs 150-250mU/mg protein that discloses asialylated-AGP people (1982) J.Biol.Chem.257:13845-13853 such as () Weinstein.These early stage researchs show that together ST6Gal I sialyltransferase need surpass 50mU/mg and sialylated fully to realize up to 150mU/mg.

The present embodiment proof need be than expection enzyme still less to the sialylated of recombinant glycoprotein with ST3Gal III sialyltransferase.For the reaction of a kilogram levels, need the ST3GalIII sialyltransferase of about 7,000 units, rather than shown 100 in the early stage research, 000-150,000 unit.These enzymes are unpractical from the purifying of natural origin, only obtain the output of 1-10 unit in mass preparation after 1-2 month.Suppose that ST6Gal I and ST3Gal III sialyltransferase all are to produce as the reorganization sialyltransferase, and realized the identical expression of two enzymes, with respect to ST3Gal III sialyltransferase, ST6Gal I sialyltransferase needs the fermentation scale of 14-21 doubly high (or higher) so.For ST6Gal I sialyltransferase, reported the expression of 0.3U/l in the yeast (people (1995) Biochem.Biophys.Res.Commun.210:14-20 such as Borsig).In aspergillus niger, realized the expression that ST3Gal III sialyltransferase 1000U/ rises.On existing expression, will need 300-450,000 liter culture propagation thing carries out sialylated needed enough enzyme with ST6Gal I sialyltransferase to 1kg glycoprotein to produce.On the contrary, with ST3Gal III sialyltransferase 1kg glycoprotein is carried out sialylated needs and be less than 10 liters of fermentation of Aspergillus niger things.Thereby, produce the required fermentability ratio of ST3Gal III sialyltransferase that is used for extensive sialylated reaction and produce the required low 10-100 of ST6Gal I doubly; The cost of producing sialyltransferase will reduce pro rata.

Result of experiment is described now.

Being expressed in the natural sugar form of the Cri in the human myeloma cell. the Cri-IgG1 antibody of purifying contains indefinite sugar form from the patients serum who suffers from Huppert's disease.Figure 97 A-97C has shown the HPLC curve of the glycan that enzymatic discharges from Cri-IgG1 antibody.Figure 98 A-98C has shown the MALDI curve of the glycan that enzymatic discharges from the Cri-IgG1 antibody that is expressed in human myeloma cell.Main form is G0, the G1 of galactosylation deficiency, and G2 is relative few (table 14 and Figure 97 C) with sialylated structure.For the influence to mab treatment character of the glycan of checking modification, external exoglycosidase is pruned and external glycosylation reconstruct is modified Cri-IgG1 antibody by carrying out, to generate the different sugar form of this antibody.

The relative quantity of the Cri-IgG1 different sugar form that the human myeloma cell that table 14. separates by HPLC is expressed is that the area from separately peak calculates and gets.

At first, (each 100 μ g) are carried out in the optimization of each step in exoglycosidase pruning and the glycosylation on small-scale.

Three mannose core sugar forms (M3N2) of Cri-IgG1 antibody. the progressively processing by glycosidase generates M3N2, and this glycosidase comprises neuraminidase, β 1,4-galactosidase and β 1-2,3,4,6N-acetyl hexosaminidase.For the removal of terminal galactose and G1cNAc on the Cri-IgG1 antibody sample of estimating sugared reconstruct, used quantitative Capillary Electrophoresis (CE) method.Glycan is to discharge with PNGase F enzymatic from the antibody of sugared reconstruct, and with 8-amino pyrene-1,3,6-trisulfonic acid (APTS) carries out derivatization at reducing end under neutral.The CE of the fluorescence detection (LIF) of the product of gained by having induced with laser on the post analyzes (Ma ﹠amp as a result; Nashabeh, 1999, the same).Because the separation of glycan is based on the difference of hydrodynamics size, so the glycan of APTS mark moves (M3N2＜M3N2F＜G0＜G1＜G2) with the order that size increases gradually.

Figure 99 A-99D shows the glycan that discharges from the Cri-IgG1 antibody of sugared reconstruct and with the electrophoretogram of the glycan reference material (Figure 99 A) of APTS derivatization.Sugar form is identified by its electrophoretic mobility and reference material are compared.The relative quantity of each glycan kind is that the relative area percentage calculation from the peak shown in each gets, and the results are shown in the table 15.The M3N2F sugar form is represented 91% DEAE-Cri glycan, 80% SPA-Cri glycan and 100% Fc-Cri glycan.In glycan structures, observe the incomplete removal (referring to table 15) of the GlcNAc part that causes the GnT-I-M3N2F sugar form from DEAE-Cri (8.6%) and SPA-Cri (～20%).Sugar form GnT-I-M3N2F is the M3N2F sugar form with an extra GlcNAc, as being added by GnT-I.

Table 15. has calculated the area at the independent peak of CE curve among Figure 99, and has determined the relative quantity of M3N2F and GnT-I-M3N2F sugar form.

Taking off the sugar form (G0) of galactosylation. the Cri-IgG1 antibody with G0 sugar form is that the 4-galactosidase is progressively handled natural Cri-IgG1 antibody and obtained by usefulness neuraminidase and β 1, and each reaction was carried out 24 hours.Analyze by CE, HPLC and MALDI from the glycan that the antibody of sugared reconstruct discharges.Figure 100 A has shown the CE curve of the glycan that discharges.In all three samples, only observed a peak, based on reference material relatively with this peak called after G0 sugar form (Figure 100 A and table 16).

The relative quantity of the Cri-IgG1 G0 sugar form that table 16. is determined by CE and HPLC.

Except the glycan analysis that is provided by CE, quantitatively the HPLC method also is used for determining the percentage by the G0 sugar form of the reconstruct glycan representative of Cri-IgG1 antibody.It is by discharging glycan with PNGase F enzymatic and monitoring at the product that the reducing end under neutral derivatization discharges with 2-ortho-aminobenzoic acid (2-AA) that glycan on the sugar reshaped antibody distributes.The mixture of derivatization separates by HPLC having on the Shodex Asahipak NH2P-504D post of fluorescence detection.Figure 101 A-101C shows the chromatogram that obtains from the glycan that discharges.Owing in all three samples, only found a main peak, so HPLC result has confirmed the CE analysis.With CE and HPLC data consistent, maldi analysis shows that also almost completely sugar is reconstructed into G0 sugar form (Figure 102 A-102C).

The G2 sugar form (G2) of complete galactosylation. handle Cri-IgG antibody to obtain the taking off sialic acid sugar form with neuraminidase, this sugar form also is the galactosylation deficiency.Use 0.6U/

ml ox β

1,4 galactosyltransferase and galactose donor molecule to handle these then and take off the sialic acid sugar form, have the G2 sugar form so that antibody sugar is reconstructed into.

The degree of terminal galactose baseization is determined by glycan analysis.In CE and HPLC curve, only observe a main peak (Figure 103 A-103C and Figure 104 A-104C).This peak is corresponding to the G2 sugar form in each situation.The calculating of percentage total peak area shows that almost completely (～90%) changes G2 (referring to table 14) into from the not enough sugar form of galactosylation of original sample.These the results are summarized in the table 17.The maldi analysis of glycan further is supported in all samples almost completely, and sugar is reconstructed into G2 sugar form (Figure 105 A-105C).

The relative quantity of the reconstruct Cri-IgI1 antibody G2 sugar form that the percentage total peak area was determined during table 17. was analyzed by CE and HPLC.

GnT-I-sugar form (GnT-I-M3N2). by add a GlcNAc part to molecule M3N2 sugar form Cri-IgG antibody sugar is reconstructed into the GnT-I-M3N2 sugar form.This molecule and 25mU GnT-I/mg antibody are contacted with suitable GlcNAc donor molecule.CE, the HPLC of the glycan that discharges and maldi analysis (being respectively Figure 106 A-106D, Figure 107 A-107C and Figure 108 A-108C) show that original M 3N2F sugar form is by reconstruct fully.Yet the modification structure that 40-60% is only arranged is the GnT-I-M3N2 sugar form, and about 30% is the G0 sugar form.The existence of G0 sugar form may be the result that incomplete GlcNAc prunes when preparation original M 3N2 form.

Five equilibrium sugar form (NGA2F). combination by making M3N2 sugar form Cri-IgG antibody and three kinds of transferase GnT-I, GnT-II and GnT-III and suitable N-acetyl-glucosamine donor molecule contact and its sugar are reconstructed into the NGA2F sugar form.Be reflected in 24 hours and finish.In order to determine that five equilibrium-G1cNAc partly adds the degree in the glycan to, use CE and analyze the sugar form of determining to be present on the sugared reshaped antibody.

Figure 109 A-109D shows the electrophoretogram of analyzing acquisition from the CE of the glycan of the Cri-IgG1 antibody release of sugared reconstruct.4 peaks have appearred after reconstruct.A main peak is to move with the identic retention time of NGA2F standard sugar.3 other secondary peaks may be the glycan of incomplete reconstruct.In order to compare, also used quantitative HPLC method, wherein the sequentially eluting that increases gradually with size of the glycan of 2-AA mark (Gn1＜G0＜NGA2F).Shown in Figure 110 A-110C, from the CE analysis of glycan, obtained similar result.Use CE or HPLC analysis and all do not find M3N2F.The NGA2F glycan is the main peaks that CE and HPLC analyze.Still the Gn1 and the G0 glycan that are retained in the sample may be the results who not exclusively modifies.Most of original M 3N2F sugar forms partly are reconstructed into NGA2F sugar form (60～70%) by 3 GlcNAc, about 15～18% partly are reconstructed into the G0 sugar form by adding 2 GlcNAc, and only have a small amount of (～7%) partly to be reconstructed by only adding a GlcNAc.The maldi analysis (Figure 111 A-111C) of the glycan that discharges shown have 1, the peak of the sugar form of 2 or 3 terminal GlcNAc parts, it is consistent with CE and HPLC analysis (Figure 109 and 110).The relative quantity of each glycan kind is that the relative area percentage calculation from peak shown in each gets, and is summarized in the table 18.

Table 18. is determined by CE and HPLC from the relative quantity of the different sugar form of the Cri-IgG1 of GnT-I, II and III reconstruct.

38. high mannose N-glycan is reconstructed into N-glycan heterozygosis and complexity: ox pancreas RNase

Present embodiment has proposed the preparation to the ox pancreas RNase with N-glycan heterozygosis or complicated.The high mannose N-of RNase connected glycan carries out enzymatic digestion and the N-that handles with the generation heterozygosis is connected glycan.In addition, can carry out enzymatic digestion to the high mannose N-connection glycan of RNase and be connected glycan with handling to generate complicated N-.

The high mannose structures of N-connection oligosaccharides can be modified to heterozygosis or complicated form with the combination of alpha-Mannosidase and glycosyl transferase in the glycopeptide.Present embodiment has been summed up with the result of simple N-glycan as this effort of model substrates.

The glycopeptide that the ribonuclease B of purifying (RNaseB) (Sigma) is made up of 124 amino acid residues from Pancreas Bovis seu Bubali.It has the single potential N-glycosylation site of being modified by high mannose structures.Because its simplicity and low-molecular-weight (13.7kDa～15.5kDa), so the good candidate of the possibility of ribonuclease B is a proof connects oligosaccharides to heterozygosis or complicated N-from high mannose structures N-glycan reconstruct.The MALDI-TOF of RNaseB spectrum (Figure 180 A) with show by the HPLC figure (Figure 180 B) of N-dextranase from the oligosaccharides of RNaseB cutting: except that the fraction of the peptide of unmodified, most of N-glycosylation sites of peptide all use the high mannose oligosaccharides of being made up of 5～9 mannose residues to modify.
