Sequence identity or sequence homology

The purposes that any nucleotide sequence with the amino acid sequence of polypeptide of the concrete property with this paper definition or this peptide species of encoding has the sequence (hereinafter referred to as " homologous sequence ") of sequence identity to a certain degree or sequence homology is also contained in the present invention.In this article, term " homology " refers to that a certain entity and subject amino acid sequence and theme nucleotide sequence have certain homology.In this article, term " homology " can be equal to " identity ".

In this article, think that homologous sequence comprises that with subject nucleotide sequence can be at least 75,85 or 90% identical, preferred at least 95 or 98% identical aminoacid sequence.Usually, homologue will comprise the avtive spot identical with the subject amino acid sequence etc.Although homology also can be regarded similarity (amino-acid residue that promptly has similar chemical property/function) as, in content of the present invention, preferably homology is stated as sequence identity.

In this article, think that homologous sequence comprises that with the nucleotide sequence (subject nucleotide sequence) of code book invention polypeptide can be at least 75,85 or 90% identical, preferred at least 95 or 98% identical nucleotide sequence.Usually, homologue will comprise the sequence of the coding avtive spot identical with subject nucleotide sequence etc.Although homology also can be regarded similarity (amino-acid residue that promptly has similar chemical property/function) as, in content of the present invention, preferably homology is stated as sequence identity.

Can estimate and carry out homology relatively, perhaps more usually by the sequence comparison program that is easy to obtain.These commercial computer programs can calculate the % homology between two or more sequences.

Can calculate the % homology to adjoining sequence, be about to a kind of sequence and other sequence compares, and each amino acid in a kind of sequence and the corresponding amino acid in other sequence are directly compared, whenever next residue.This is called " non-notch " contrast.Usually, only to carry out this non-notch contrast than short number purpose residue.

Although this is a kind of very simple and reliable method, yet it for example fails to consider that in the identical paired sequence of others one is inserted or deletion will cause that the amino-acid residue of back can't compare, and may cause thus that the % homology reduces greatly when carrying out overall contrast.Therefore, most of sequence comparative approach are designed to generate best contrast under the situation of considering possible insertion and deletion, excessively do not punish whole homology score.This is by inserting " breach " to manage that local homology's maximization is realized in the sequence contrast.

Yet, these complicated more methods give " breach point penalty " for each breach that takes place in the contrast, make that for the same amino acid of similar number the sequence contrast (having reacted the high correlation between two kinds of comparative sequences) with the least possible breach will obtain more to many other sequence of breach and contrast higher score than having.Usually use " affine breach cost (Affine gap costs) ", promptly higher cost is sentenced in the existence of breach, and each the follow-up residue in the breach is sentenced less point penalty.This is the most frequently used breach points-scoring system.High breach point penalty will generate with less breach certainly optimizes contrast.Most of contrast programs are allowed change breach point penalty.Yet, when using this software to carry out the sequence comparison, preferably use default value (default value).For example when using GCG Wisconsin Bestfit software package, the default breach point penalty (default gappenalty) of aminoacid sequence is that breach-12 and each extend to-4.

Therefore, the calculating of maximum % homology at first needs to generate best contrast, wherein will consider the breach point penalty.Be applicable to carry out this correlated a kind of computer program be GCG Wisconsin Bestfit software package (people such as Devereux, 1984, Nuc.Acids Research, 12:387).The example that can carry out other software of sequence comparison includes but not limited to that the BLAST software package (sees people such as Ausubel, 1999, Short Protocols in Molecular Biology, the 4th edition, the 18th chapter), FASTA (people such as Altschul, 1990, J.Mol.Biol.403-410) and GENEWORKS compare tool cover.BLAST and FASTA can both carry out off-line and on-line search (see people such as Ausubel, 1999,7.58-7.60).Yet,, preferably use GCG Bestfit program for some application.Can also use a kind of new tool that is called BLAST 2Sequences to come comparison protein and nucleotide sequence (to see FEMS Microbiol Lett1999,174 (2): 247-50; FEMS Microbiol Lett 1999,177 (1): 187-8, And tatiana @ncbi.nlm.nih.gov).

Although final % homology can be measured according to identity, yet comparison process self is not based on " be entirely or non-entirely " paired comparison usually.But, use yardstick similarity rating matrix relatively to give score to every pair usually according to chemical similarity or evolutionary distance.An example of this matrix commonly used is the default matrix of BLOSUM62 matrix-blast program cover.The symbol comparison sheet (if providing) (further details is seen user manual) of disclosed default value or customization is provided GCG Wisconsin program usually.Use for some, preferably use the open default value of GCG software package, perhaps in the situation of other software, use default matrix, such as BLOSUM62.

Perhaps, can use with CLUSTAL (Higgins DG and Sharp PM, 1988, Gene73 (1): 237-244) similar algorithms be the basis DNASIS ^TMMultiple contrast characteristic in (Hitachi Software) calculates the % homology.

In case software has generated best contrast, just might calculate the % homology, preferred % sequence identity.Software is carried out it as the part of sequence comparison usually, and generates a numerical result.

Sequence can also have amino-acid residue deletion, the insertion that generates reticent change and cause function equivalent or substitute.Can carry out scrupulous amino acid replacement according to polarity, electric charge, solvability, hydrophobicity, wetting ability and/or the amphipathic essence of residue, as long as keep the less important of material in conjunction with active.For example, electronegative amino acid comprises aspartic acid and L-glutamic acid; Positively charged amino acid comprises Methionin and arginine; And the amino acid with uncharged polar head group (having similar hydrophilicity value) comprises leucine, Isoleucine, Xie Ansuan, glycine, L-Ala, l-asparagine, glutamine, Serine, Threonine, phenylalanine and tyrosine.

Can obtain the secondary structure classification by crystalline structure.This means the part that each amino acid can be included into alpha-helix or beta sheet.Figure 57 has shown the PFAM contrast of 1DEO, 1IVN and P10480 (Aeromonas hydrophila database).What add under every capable sequence is textural classification.

The PFAM database comprises the protein comparison of low sequence identity.Therefore, these contrasts are not fine.Although contrast algorithm (HAMMER preface type) is very suitable for discerning conservative motif, yet this algorithm is not fine on level-of-detail.Therefore, just between PFAM contrast and structure contrast, found differences also not very accident.Know easily as the technician, can on the basis of structured data, revise the PFAM contrast.This means and can those structural elements that overlap be compared.

Figure 55 has shown the initial PFAM contrast of 1DEO, 1IVN and P10480.What add in contrast is secondary structure information from 1DEO and 1IVN crystalline structure.Contrast 2 among Figure 56 has shown the contrast of manual modification, and wherein the coupling between the secondary structure element is improved.According between 1DEO and the P10480 or the conserved residues between 1IVN and the P10480, also revised the contrast of P10480.In order to be easy to the distinguishing sequence module, the sequence identifier in the contrast 2 has extra m (1DEOm, 1IVNm, P10480m).

Contrast 3 is mixing of 1 and 2, has provided the contrast of each module.

Embodiment 2: the structure in scanning library, site

Use Quick Change Multi Site-DirectedMutagenesis Kit promptly to change multiple site-directed mutagenesis test kit fast according to the indication of the Stratagene of manufacturers.For each library, design contains the degenerated primer of a NNK or NNS (Nucleotide abbreviation) codon.Design of primers is to use and can be undertaken by the instrument that the Stratagene website obtains.The operational analysis primer forms the standard analytical tools of hair fastener or primer dimer possibility and has further confirmed the primer quality control.

The main concept of this method is: use non-strand displacement high-fidelity DNA polymerase such as Pfu-Turbo and a primer, the linear amplification dna profiling.This is different with conventional index amplification procedure in the PCR reaction.This linear amplification process has been guaranteed low incorrect frequency.Product is non-methylate DNA of strand and double-stranded hemimethylation DNA.If template is obtained by the appropriate host organism, template is double-stranded methylate DNA so.This means and can use DpnI endonuclease enzymic digestion template DNA, and indigestion product D NA.Therefore, after being transformed into DNA in the appropriate host, the transformant that contains non-mutagenesis plasmid has only very low frequency.

Embodiment 3: select the victor by scanning library, site

Two kinds of alternativess have been described:, or after analyzing the library victor is checked order to the amino acid of library order-checking post analysis uniqueness.

Select victor's first method: to the amino acid of library order-checking post analysis uniqueness.

Select box by selecting box to replace to kantlex, by pDP66S (Penninaga etc., Biochemistry, 1995,3368-3376) derive and be used for generating site scanning library/variant and in subtilis, expressing the conversion/expression shuttle vectors of mutant intestinal bacteria.By replacing the cgt gene in P32 promotor downstream, in this carrier, insert the acyltransferase variant gene.This carrier uses the P32 promotor to drive the expression of acyltransferase variant gene in subtilis.

Use " Molecular Biological Methods for Bacillus " (C.R.Harwood and S.M.Cutting volume, 1990, John Wiley ﹠amp; Sons Ltd., Chichester, the UK) method for transformation described of the 3rd chapter, with expression vector be transformed into nprE-, aprA-subtilis DB104 (Kawamura and Doi, J.of Bacteriology, in October, 1984, p442-444).

The degeneracy oligomer that use contains a NNK codon makes up scanning library, site, and wherein K represents G or T, and N represents A, C, G or T.This means that the one group of clone (being also referred to as " scanning library, site ") who makes up by the amplified reaction that uses the NNK primer contains the codon of 32 kinds of uniquenesses (4x4x2=32 kind combination option) in principle.Suppose not exist bias, choosing once required clone's number at least with in 32 kinds of codons of possibility of 95% each so is 95.This can use following formula to calculate.

Formula 1:n={log (1-c) }/{ log (1-f) }

Wherein n refers to clone number, c refers to the decimal numerical value of fiducial interval, for example the decimal numerical value of 95% fiducial interval is 0.95 and the decimal numerical value of 99% fiducial interval is 0.99, and f refers to the frequency that each individual codon takes place, and is exactly 1/32 or 0.03125 for the NNK primer.The formula of answer n draws 94.36 or 95 clones.If think that 95% fiducial interval is too low, or in one or more steps of library construction process, can not avoid bias, can determine so more clone is detected or checks order.For example, in formula 1, if n is made as 384, f is made as 1/32 or 0.03125, and fiducial interval c is just much bigger than 99% so.If even 60% clone contains identical sudden change or wild-type codon, 363 clones will obtain all 32 kinds of codons with 99% degree of confidence so.Thus, can reach a conclusion, 384 clones will contain all 32 kinds of codons with 99% degree of confidence, and every kind of codon occurs once at least.

Carry out bacterium colony PCR (promptly bacterial colony or bacterial liquid culture are carried out the PCR reaction, thereby by the plasmid amplification fragment in the bacterium, the part to mutagenesis in the fragment checks order subsequently, this is a kind of flow process of having set up).Because can obtain the preformed material (being also referred to as test kit) of bacterium colony PCR, order-checking and sequence purifying, so can be to the daily bacterium colony PCR that carries out of 96 one group bacterium colony.Several commercial companies provide the service of this whole flow process, such as AGOWA GmbH (Glienicker weg 185, D-12489, Berlin, Germany).

After having analyzed 96 sequencing reactions, for each codon that can find in 96 sequences of this group is selected a representational individual clone.Subsequently, for each clone who represents mutant, inoculation 5ml adds LB substratum (casease digestion promoting product, the 10g/L of 50mg/L kantlex; Low sodium yeast extract, 5g/L; Sodium-chlor, 5g/L; Inertia auxiliary agent in blocks (tableting aid) 2g/L), and was cultivated 6 hours with 205rpm in 33 ℃.This culture of 0.7ml is used to inoculate the SAS substratum (K that 50ml adds 50mg/L kantlex and high malt sugar starch hydrolysate solution (60g/L) ₂HPO ₄, 10g/L; MOPS (3-morpholino propane sulfonic acid), 40g/L; Sodium-chlor, 5g/L; Antifoams (Sin260), 5/L; Defatted soyflour, 20g/L; Biospringer 106 (100%dw YE), 20g/L).In 33 ℃ continue to cultivate 40 hours with 180rpm after, by with centrifugal 30 minutes separation and Culture thing supernatant liquors of 19000rpm.Supernatant liquor is transferred in the clean pipe, and be directly used in detection.

Select victor's second method: screening is checked order to the victor behind the library.

Although can select 384 clones are checked order, yet the variant that also can before order-checking, test and select to improve to them.

When screening so many sample, should consider many problems.Though not exhaustive, though the variant that might select the activity to a kind of substrate to change to some extent, the difference of expression level may be huge between 384 parts of cultures, even in the situation of using 384 hole microtiter plates, cause background higher.Therefore, measure two kinds of activity and to select the victor according to ratio vary be a kind of preferable methods.For example, if two kinds of activity have certain ratio R, no matter so the absolute quantity that enzyme exists, the ratio between two kinds of activity will be R all the time.Another kind of active sudden change has taken place to change with respect to a kind of activity in the variation indication of R value.

Figure 60 has shown the data set that is obtained by scanning library, site.All clones have been tested activity to phosphatidylcholine (PC) and digalactosyl triglyceride (DGDG).Show that all clones that R value do not change (may be suddenlyd change or do not suddenly change) will be positioned on the straight line with certain error span.No matter these clones, Figure 61 has shown three concern groups.

First zone of Figure 61 is contained R and is significantly higher than wild-type (not sudden change) but overall all lower clones of DGDG activity.R value and all high than the wild-type mutant of DGDG activity are contained in second zone.The 3rd zone contains that the R value does not have to raise but the active clone who significantly raises of DGDG or PC.

If pay close attention to the variant to the activity rising of DGDG, most interested variant is contained in second zone so, and interested variant is also contained in the 3rd zone.Show that the trizonal variant that hydrolytic activity raises greatly may be accompanied by the transferase active reduction.

Have something to merit attention, if hit a specific residue of decision, 20 kinds of major parts in may amino acid can produce very different R values so.Yet if the library has at some amino acid whose very big bias (for example 60% is tyrosine), all that variant will be positioned on the straight line so.
