Description

Cellulase, its encoding gene and application thereof
Background of the present invention
The field of the invention:
The present invention relates to encode new neutral cellulase gene and contain the composition of new neutral cellulase. These compositions are at textile, and are particularly useful in detergent and paper pulp and the paper industry.
Correlation technique:
Cellulose is the line style polysaccharide by the glucose residue of β-Isosorbide-5-Nitrae key connection. At nature, cellulose usually and lignin and link such as the hemicellulose of xylan and glucomannans. The characteristic of known fiber element enzyme has hindered the practical application of cellulase, and these cellulases normally have the mixture of the cellulase of various activity and substrate specificity. Therefore, need to identify the source of the cellulase that can obtain only to have required activity.
Be known in the art the cellulase of numerous kinds, wherein great majority are acidic cellulases. Yet, also identified some neutrality and alkali cellulose enzyme. CelluzymeCommercially available cellulase goods from Humicola insolens (Novo Nordisk, A/S). GB2,075,028 and EP406,314 described Humicola insolens cellulase as the enzyme additive in the washing detergent to reduce the roughness (stiffness index) of cotton-containing fabrics. Contain from Humicola insolens the endoglucanase activity cellulase be cloned in WO 93/11249 and EP531, describe in 372. EP510,091 has described the cellulase from bacillus NCIMB 40250 useful in detergent compositions. EP220,016, described as the useful cellulase of fining agent of yarn dyed fabric. WO94/07998 has described has the cellulase that improves the active modification of alkalescence. WO95/02675 has described the detergent compositions that contains two kinds of different cellulases: the first cellulase plays the effect of dust removal grain in catalysis; The second cellulase plays the color clarification in catalysis. WO92/18599 has described the detergent goods of cellulase and protease. Cellulase is also stuck with paste thickener and unnecessary dyestuff (EP576,526) industrial for the printing and dyeing after helping to remove fabrics printing and dyeing.
EP383,828 have described the graininess detergent compositions, and it contains surfactant, fabric softening clay material, and cellulase particle calciferous. US5433750 has described and has contained surfactant, increases the material system of cleaning action, softening clay, clay flocculating agent and high active cellulase, the detergent compositions of preferred Humicola insolens cellulase. The graininess detergent compositions that US5520838 describes comprises surfactant, increase material and the cellulase of cleaning action, preferred Humicola insolens cellulase, said composition is a kind of closely form, has quite high density and contains a small amount of inorganic fill salt.
Also be used for the industry of numerous species except industrial textile outer fiber element enzyme. For example, cellulase is in industrial deinking for newspaper and magazine (EP521,999). For improvement of the sewage (WO91/14822, WO91/17243) of paper pulp and as the processing to animal feed.
The unique property of each cellulase makes some cellulase more be applicable to certain purpose than other. Although this enzyme distinguishes in many ways, most important difference be the pH amount just when. Neutral cellulase has useful cellulase activity in pH scope 6-8, alkali cellulose enzyme has useful cellulase activity in pH scope 7.5-10. Acidic cellulase has activity in the pH4.5-6 scope, but has very little cellulase activity when higher pH value.
Neutrality and acidic cellulase are particularly useful in industrial textile. Klahorst, S. etc., textile chemist and colorist, 26:13-18,1994; Nilsson, T.E., the meeting of Aachen textile, DWI reports 114:85-88 (1995); Videbrek, T etc., ITB dyeing/printing and dyeing/polishing, in January, 1994,25-29 page or leaf; Klahorst, S, etc., AATCC international conference and exhibition, 4-7 day in October, 1992, the 243rd page, Atlanta, GA; Kochavi, D etc., american dye information, September nineteen ninety, 26-28 page or leaf; Tyndall, R.Michad, textile chemist and colorist 24:23 (1992); Lange, N.K, the procceedings of the TRICEL symposium second time of Trichoderma reesei cellulase and other hydrolase, Espoo, Finland, 1993, editor. P.Suominen etc., biotechnology and industrial fermentation WARF, the 8th volume, 1993, the 263-272 pages or leaves. When for the treatment of fabric, cellulase is attacked the cellulose molecular chain that forms cotton fiber, thereby affects the characteristic of fabric.
Traditionally, in " wearing away ", float stone is used for changing the characteristic of fabric. Little by little, cellulase has replaced float stone, and float stone also makes fabric produce required FINAL APPEARANCE, but it can cause to machinery the damage of clothes and sewage processing unit (plant). US4832,864, US4912056, US5006126, US5122159, US5213581 and EP307564 disclose the application of cellulase in biology is worn away.
Cellulase is particularly useful for the denim goods of wearing away with indigo dyeing, because these dyestuff great majority are positioned at the surface of yarn and do not penetrate fiber holes. When for the treatment of bafta, the neutral cellulase wash time longer than acid cellulose enzyme require in general. Yet obtainable neutral cellulase has less offensiveness (activity) than acidic cellulase to cotton fabric, and it is reported and do not resemble the such easy damage fabric intensity of acidic cellulase. Neutral cellulase has wider pH scope, and it is very little that the pH that therefore occurs during biology is worn away increases the impact of centering enzymatic activity.
Since acidic cellulase promote fabric redye (back staining) and frangible tendency has hindered its application. In addition, pH must be transferred in the scope that is suitable for acidic cellulase performance function. Therefore, clearly need a kind ofly not cause that fabric is redyed or frangible neutral cellulase goods.
Although in industrial textile, use cellulase to become more and more general, change simply employed cellulase mixture and can produce different polish results. These problems will more and more be concentrated in the research to the repeatably cellulase mixture with required feature. Therefore, very clear need to have activity especially when neutral and alkaline pH are planted in textile and detergent industry, do not damage fabric intensity, has the new cellulose enzyme of cleaning preferably and/or fabric protection and reduction roughness characteristic.

Genetic sequence by the clones coding desired protein and help method for genetic modification host of the present invention by expressing this genetic sequence. Nucleic acid molecules (preferred DNA) attempted to refer in term used herein " genetic sequence ". The genetic sequence of coding desired protein is from various sources. These sources comprise genomic DNA, cDNA, synthetic DNA and combination thereof. Can use the carrier system generation for the production of the host of enzyme preparation of the present invention. This vector construction body (a) can further provide a kind of vector construction body (b) of separation, the required gene of construct (b) coding host genome at least a to be integrated into and with (a) or (b) (c) selected marker of coupling. In addition, the carrier of separation can be used for mark.
If the nucleic acid molecules such as DNA contains expression control sequenc, then be called " can express " polypeptide, wherein this expression control sequenc contains the nucleotides sequence that transcriptional regulatory information and this sequence " be effectively connected to " coded polypeptide and lists.
Effectively connect expression that to be a certain sequence make this sequence with a connected mode of regulating sequence (or a plurality of adjusting sequence) being connected in the impact of this adjusting sequence or under controlling. If if promoter function induce the sequence mRNA that causes coded protein to transcribe and two dna sequence dnas between connection character can (1) not cause importing frameshift mutation, (2) disturb expression to regulate sequence-directed mRNA, the ability of antisense RNA or protein expression or (3) are disturbed and are activated the template ability that the subregion sequence is transcribed, and then claim two dna sequence dnas (such as protein coding sequence and the promoter region sequence that is connected coded sequence 5 ' end) effectively to connect. Therefore, this promoter region effectively is connected with dna sequence dna if promoter can affect transcribing of dna sequence dna.
The definite character of the adjusting sequence that gene expression is required changes between kind or cell type, but generally must comprise and relate separately to 5 ' non-transcribed and 5 ' untranslated (non-coding) sequence of transcribing with translation initiation. Protein expression need to use the control band that function is arranged in this host in transforming the host. Can adopt many various adjusting sequences of transcribing and translate. In eucaryote, do not link to each other if transcribe with translating, whether contain this methionine according to clone's sequence, this control zone can provide or not provide initial methionine (AUG) password. In general, this zone comprises is enough to instruct the synthetic promoter region of host cell starting RNA.
As everyone knows, the translation of eukaryotic mrna starts at the codon place of coding the first methionine. Therefore, guarantee that preferably the bonding pad between the DNA sequence of eukaryotic promoter and coded protein or its functional derivatives does not contain any codon that interleaves of the methionine of encoding. The existence of this codon causes forming fusion (if the dna sequence dna of AUG codon and coded protein is in same reading frame) or frameshift mutation (if the sequence of AUG codon and coded protein is not in same reading frame).
In preferred embodiments, desired protein is owing to existing secretory signal sequence to secrete in culture medium on every side. If desired protein is not that burst itself is arranged, if or this burst can not in the host, bring into play well function, the sequence of coded protein can be effectively connected to so on the burst with host's homology or allos. Required coded sequence can link to each other with any burst that allows this protein of secretion from the host. This burst can be designed to contain or do not contain the specific protease site, and this signal peptide sequence is removed easily subsequently. In addition, can use protein is leaked to host in the culture medium, for example, have the host of sudden change at its film.
If necessary, can obtain the sequence 3 of coded protein ' do not transcribe and/or untranslated region by above-mentioned cloning process. Can keep 3 '-tanscription termination of nontranscribed domain regulates sequential element; Can keep 3 '-translation termination of non-translational region regulates sequential element or it instructs those elements of polyadenylation in eukaryotic.
Carrier of the present invention also can comprise other regulating element such as enhancer sequence that effectively connects.
In preferred embodiments, make up the upper stable transformant of heredity, with this required protein dna is integrated in the host chromosome. The coded sequence of desired protein can be from any source. From the beginning this integration can occur in cell, perhaps, and in most of preferred embodiments, help this integration through transforming with carrier, this carrier inserts host chromosome with himself on function, for example, have the DNA element that promotes that dna sequence dna is integrated in chromosome.
Also advance its chromosomal cell through importing the DNA stable integration that the one or more marks allow to be chosen in the host cell that contains expression vector in the chromosome select to import, for example, this mark can provide the biocide resistance, for example, to antibiotic, or heavy metal, such as the resistance of copper etc. Selectable marker gene can be directly links to each other with DNA gene order to be expressed or imports in the same cell through cotransformation.
Important factor comprises in selecting certain plasmid or viral vectors: identify and select to contain the convenience of the recipient cell of carrier with it from carrier-free those recipient cells; Required carrier copy number in specific host; Whether need this carrier that between different types of host cell, " to shuttle back and forth ".
In case prepared the construct that is used for the carrier of expressing or contains dna sequence dna, available various arbitrarily suitable methods comprise that aforesaid conversion imports suitable host cell with DNA construct. After importing carrier, growth receptors cell in the selection culture medium of selecting transformed cell growth. The fragment that the expression of clone's gene order causes producing required protein or produces this protein. Can in transformant, carry out this expression in a continuous manner or in the mode of control.
Therefore, the sequence of coded protein as herein described can be effectively connected on the required arbitrarily carrier and transform among the selected host, so that the expression of this protein in the host to be provided.

Determine to wear away effect through the enhancing of measuring brightness and Lan Se as the catoptry in fiber front, redye (the again deposition of fiber surface indigo) and be determined as the blue look enhancing of reverse side and brightness decline. When pH7, the neutral cellulase of ALKO 4237 causes front face brightness and blue obviously enhancing and does not observe and redye (Fig. 6 A and 6B). When pH5, find similar wear away effect but slight redying arranged. When pH7, another neutral cellulase ALKO 4265 strengthens positive blueness but strongly redyes at reverse side. When pH5, observe similar effect with ALKO 4265 with ALKO 4237 goods. When pH7, acidic cellulase is not redyed or is reduced front face brightness (when using the endoglucanase active dose similar with ALKO 4265 and ALKO 4237, Fig. 7 A and 7B, 1 * dosage), is likely because of it does not play a role under this pH. On the other hand, when pH5, positive brightness and Lan Se strengthen and observe significantly at reverse side and redye. According to these results, under two kinds of pH values, can occur redying according to used cellulase goods.

Fig. 8 has shown the SP-Sepharose that is loaded to the 25mM sodium acetate pH4.0 that contains 1mM EDTA of 150ml/h when this protein of 11.7gTM4.5 * 31cm post on and the result that obtains of the post that forms with 75ml/l from the 0.0 line style gradient that obtains 0.4M NaCl of having in 3.4 liters of same buffer. Elute most of endoglucanase at 0.2M NaCl place. Use is measured in the improvement described in the embodiment 10. When active fractions is stored in 7 ℃, crystalline deposit occurs therein and almost contain whole endoglucanases activity. Crystallization slowly active fractions (15ml) is induced the formation crystal through control oneself 30 μ l suspensions of the cut that contains crystallization of inoculation. After 2 to 3 days, through centrifugal collection crystal, use the 25mM PIPES/KOH pH6.0 washing that contains 1mM EDTA and be dissolved in the 25mM Tris/HCl pH7.2 that contains 0.25mM EDTA. Analyze to show that through SDS-PAGE the crystallization of washing contains apparent molecular weight near the basically homogeneous protein of 20kDa (error of the SDS-PAGE of molecular weight in estimating be at least ± 10%, may be larger for unusual protein). This protein is called the 20K-cellulase. Through the G50Sephadex in containing the 50mM PIPES/KOH pH6.0 of 1mM EDTATMUpper gel filtration also can be removed contaminating protein matter. Its example shows in Fig. 9, wherein through the unwashed crystal of gel filtration purifying. Endoglucanase activity with the common wash-out of 20kDa protein behind cromoci (11.2kDa) volume shows this 20kDa protein process and SephadexTMInteract and exception deferral.
With the protein among the ammonium sulfate precipitation peak III/IV and with II protein described identical mode in peak is converted to the 25mM sodium acetate pH4.0 that contains 1mM EDTA. When converting 25mM sodium acetate pH4.0 to, a large amount of precipitations of formation are also discarded. Active supernatant is at SP-SepharoseTMUpper classification separates. Be loaded on 2.5 * 11cm post with epsilon protein (for example 200mg protein) as shown in figure 10, most of endoglucanase activity are incorporated on the post and with the NaCl gradient elution of about 50mM NaCl. This Peak Activity then is the second peak of inactive protein matter.
SDS-PAGE analyze to show active and the non-activity peak all contains some protein, comprises that the apparent molecular weight that can not distinguish mutually with SDS-PAGE is near the protein of 50kDa. With at Phenyl SepharoseTMOn chromatogram be further purified two peaks.
Merge active fractions (cut 15 to 18 among Figure 10), transfer to 50mM PIPES/KOHpH6.0 (through adding 0.25M PIPES/KOH pH6.0) and 15g% ammonium sulfate (through adding solid ammonium sulfate) and be loaded to the Phenyl Sepharose that uses the 25mM PIPES/KOH pH6.0 balance that contains 1mM EDTA and 15g% ammonium sulfateTM1.5 * 8.5cm post on. The line style gradient from 15 to 0g% ammonium sulfate that is used among the 104ml 25mM PIPES/KOH pH6.0 is crossed post. When gradient finishes, with the further column scrubber of 25mM PIPES/KOH pH6.0. Wash out two protein peaks in gradient, first is the small peak of inactive protein matter, then is the main peak that contains most of endoglucanase activity. SDS-PAGE analyzes (Figure 11 A and B) and shows that two peaks contain apparent molecular weight near the basically homogeneous protein of 50kDa (that is, they are that the BioRad of the 47kDa ovalbumin standard items migration of dying in advance is slightly slow than apparent molecular weight). Can not distinguish this two kinds of protein through the inventor's SDS-PAGE analysis, can not distinguish even walk together electrophoresis when them as mixture. Protein in the Peak Activity is called the 50K cellulase, and the protein in the nonactive peak is called the 50K-PROTEIN B. Through separation by top to the described identical mode of active fractions at Phenyl SepharoseTMUpper from SP-SepharoseTMSecond (nonactive) peak (cut 19 to 23 among Figure 10) of wash-out obtains more substantial 50K-cellulase B.
Through loading SP-SepharoseTMPost helps to produce more substantial 50K-cellulase and 50K-cellulase B. For example, be loaded to 4.5 * 31cm SP-Sepharose when 15g proteinTMWhen upper, the 50K-cellulase is obviously replaced by the protein of stronger combination and is eluted before not being incorporated in the NaCl gradient with the post knot. This material is by highly purified, and through as mentioned above at Phenyl SepharoseTMUpper chromatography is therefrom isolated homogeneous 50K-cellulase.
In order to accelerate the large-scale purification of 50K-cellulase, put upside down SP-Sepharos and Phenyl Sepharose post. Regulate ammonium sulfate concentrations to about 15g%, the protein that will precipitate in peak III/IV is loaded on the Phenyl Sepharose as previously mentioned. When applied sample amount is higher (for example, 17g protein is loaded on 3.2 * 25cm Phenyl Sepharose post), most of gross protein flows through post, but 50K-cellulase (it is active to contain most of endoglucanases) combination, and the 15 line style gradient end wash-outs to 0g% ammonium sulfate in 25mM PIPES/KOH pH6.0. Western with the rabbit anti-serum of identifying 50K-cellulase B the analysis showed that 50K cellulase B is wash-out before the 50K-cellulase just. Through realizing being further purified by noted earlier the separation at SP-Sepharose. In the situation of this SP-Sepharose and Phenyl Sepharose reversed order, can will directly be loaded in next purification step without desalting with the protein among the peak III/IV of ammonium sulfate precipitation. The a large amount of protein precipitations that occur in the time of so also can avoiding among the peak III/IV concentrated protein to be directly changed into 25ml sodium acetate pH4.0 for SP-Sepharose. Because the 50K-cellulase is only in conjunction with SP-Spharose, the obvious interference of front gross protein of loading on the separation that Phenyl Sepharose carries out significantly reduces SP-Sepharose.
In Launder-Ometer, test respectively 50K-cellulase and 50K-cellulase B and whether be responsible for the beneficial effect of the peak IV that reported among the embodiment 10 to observe them. Find that two kinds of protein all have beneficial effect (Table VI). When using low concentration in this experiment, they itself do not increase indigo dye from the release of denim goods outer surface (namely, the L front does not increase), but they effectively reduce dyestuff redye the inner surface of denim goods (the L reverse side become more on the occasion of and the b reverse side become less), particularly when using with the 20K-cellulase.
20K-cellulase effect is better when pH5 reaches at pH7 in the Launder-Ometer test. When pH5, the 20K-cellulase of every gram denim goods 0.2mg is increased to 5.2 with the L front from 3.2. Add the 50K-cellulase with the 20K cellulase with the amount of the every gram denim goods of 0.1mg and also reduce redying when the pH5 (L reverse side and b reverse side 0.0 and 2.6 1.3 and 1.5 when becoming respectively the mixture of usefulness 20K-and 50K-cellulase from only with the 20K-cellulase time).

The feature of 20K-cellulase
Although (called after resists-EGI the polyclonal antibody for preparing for the cellulase from Trichoderma reesei purifying, anti--CBHI and anti--CBH II antibody) identify the protein in ALKO 4237 growth mediums, but with pure 20K-cellulase extremely weak cross reaction is only arranged in the Western engram analysis under the same conditions.
When the antiserum for pure 20K cellulase that produces in rabbit is surveyed from the growth medium of ALKO 4237 in Western analyzes, except the strong band of also observing at about 35kDa place of 20kDa band. It is active that this 35kDa protein is not detected obvious endoglucanase. In addition, near the 20kDa band, see weak band (Figure 14).
ALKO 4124 produces almost the banding pattern identical with ALKO 4237, shows that it and other fungi probably contain the cellulase closely similar with 20K-cellulase of the present invention.
Amino acid sequence from 20K-cellulase pancreatin peptide shows in Figure 17.
The 20K-cellulase of purifying is in the biology of neutral pH is worn away when not adding other enzymatic activity, and effect is better, as shown in Table VII.

And the less fabric backing (L reverse side=-0.5 is with respect to-2.9, b reverse side=3.6, with respect to 5.5) of redying. The fabric of processing with the 20K cellulase has satisfied tender texture.
Although the 20K-cellulase without other additive produces wonderful good effect, as 20K and DEAE-Sepharose amalgamation liquid I, III or IV produce better appearance of fabrics and quality (Table VIII) when using together.

20K-cellulase and amalgamation liquid I, the mixture of III and IV produce the outward appearance of brighter (it is positive to increase L) than arbitrary independent composition. At least for the combination of 20K-cellulase and amalgamation liquid IV, very clear is owing to synergy is not only the effect of increase. And, with redying in fact than only redying little (L reverse side corrigendum, the b face is less) with what the 20K-cellulase was observed of all mixtures. The combination of 20K and amalgamation liquid IV is effective especially. Amalgamation liquid IV contains numerous protein, and one of them (50kDa polypeptide) is combined at Sephadex G100 and S-Sepharose during the chromatogram of liquid IV and the active common purifying of endoglucanase. Although only realized that with the 20K-cellulase biology is worn away preferably, add that with the 20K cellulase one or more protein from amalgamation liquid IV purifying probably produce better result. The biology that carries out with 20K cellulase and mixture from the 50K-cellulase of amalgamation liquid III/IV purifying and 50K-cellulase B is worn away (the Table VI of embodiment 9) is provided. Therefore, the invention is not restricted to only use the 20K-cellulase. Other oroteins in ALKO 4237 culture mediums also is useful separately or with suitable combination.
Standard endoglucanase in descriptions such as Bailey measures (1981, loc.cit) in, select the enzyme amount, it produces about 0.6mM reduction homologue from 1% hydroxyethylcellulose enzyme under 10 minutes and pH4.8 (0.05M Na-citrate buffer solution), causing final absorptance to change (Δ A540) is 0.2 to 0.25. This head and shoulders above the amount proportional band of A540 and 20K-cellulase.
Therefore, by following update routine. Use enough enzymes in 0.05M HEPES buffer solution (pH7.0), to produce about 0.2mM reduction homologue in 10 minutes. In order to reach the critical concentration of reduction homologue, in the DNS system, forming color on this critical concentration, in the DNS reagent of storing, newly add 0.12mM glucose. When the endoglucanase of identifying 20K cellulase and 50K-cellulase is active, use the method (being called " improvement " method). Make substrate with 1% hydroxyethylcellulose, the amount proportional band of Δ A540 and 20K-and 50K-cellulase is rather narrow, and therefore 2% carboxymethyl cellulose is as alternative substrate. During with 2% carboxymethyl cellulose, the scope ratio that Δ A540 is relevant with 50K cellulase amount line style with 20K is wide with 1% hydroxyethylcellulose. The endoglucanase activity of measuring with 2% carboxymethyl cellulose with measure with 1% hydroxyethylcellulose compare for the 20K cellulase to be about 8-10 times, to be approximately 50 times for the 50K-cellulase.
Can't detect the 20K-cellulase activity for the characteristic substrate 4-methylumbelliferyl-β of the biological hydrolase of cellulose-D-lactoside. Activity to filter paper is also extremely low, but can detect.
The 20K cellulase has sizable heat endurance. With 7 μ g/ml at 25mM Tris-HCl, among the 0.2mM EDTA 100 ℃ to its insulation 30 or 60 minutes, then measure in that pH7.0 and 50 ℃ are lower. When pH7.2, keep respectively 52% and 35% of endoglucanase activity, when pH8.8, keep respectively 40% and 22%. (at room temperature measure these pH values; Actual pH at 100 ℃ is lower). At 80 ℃, during pH7.2, keep 70% activity in 60 minutes.
These results show that this enzyme is suitable for the application that enzyme wherein may (for example, accidental) be heated up. Owing to advancing at high temperature has resistance to irreversible inactivation, it is 70 ℃ (Figure 15) that this enzyme shows optimum temperature at 10 minutes duration of test of pH7.0. Being higher than that 70 ℃ of activity of observing reduce mainly is because the modulation of enzyme conformation, and this enzyme recovers that it is most of active when returning to 50 ℃.
In the time of 50 ℃, the 20K cellulase shows 80 ℃ or its larger maximum activity in 4 to 9 pH scope, be almost 50% when pH10. All like this in the mensuration of 10 minutes (Figure 16 A) and 60 minutes (Figure 16 B). These figure have also shown the pH dependence of this enzyme in the time of 70 ℃. In 10 minutes measured, in the scope of pH4.5 to 8, this enzyme had greater activity at 70 ℃ of ratios at 50 ℃, but when pH10 approximately active equal (Figure 16 A). In 60 minutes mensuration (that is, near commercial condition), between pH5.5 and 7.5, this enzyme has greater activity at 70 ℃ of ratios at 50 ℃. Yet during pH10, this enzyme is only lower slightly than activity 50 ℃ the time in the time of 70 ℃. In fact, this means that this enzyme effect of use is good equally in larger pH scope and under the temperature up at least 70 ℃.

The feature of 50K-cellulase
Pure 50K-cellulase has the biological hydrolytic enzyme activities of endoglucanase activity (to hydroxyethylcellulose) and cellulose (to 4-methylumblliferyl-β-D-lactoside, basically press van Tilbeurgh etc., at Enzymology method [1988] vol.160, measure described in the pp45-59). To be 1.8 pure enzyme sample contain 2030ECU/ml and 300PCU/ml (1PCU is the live vol that per second discharges the 1nmol methyl umbelliferone) to A280 when pH7.0 and 50 ℃.
In Western analyzes, the 50K-cellulase is identified strongly by the antiserum (KH1057) that produces for T.reesei endoglucanase I, but only by the faint identification of antiserum (being respectively KH1050 and KH1053) of the biological hydrolase I of anti-T.reesei cellulose and II. This enzyme of antiserum nonrecognition (Figure 14) for the generation of 20K cellulase. When using the rabbit anti-serum that produces for 50K cellulase itself in Western analyzes, to survey the growth medium of ALKO 4237, significantly be with except only the band that approximately 50kDa place is very strong, also seeing one (molecular weight 33 and 47kDa between).
When this protein was processed with Endoglucanases Hf, the apparent molecular weight of the 50K-cellulase of measuring through SDS-PAGE reduced about 2 to 5kDa, showed that this enzyme contains the sugar that can be removed by this Endoglucanases.
The 50K-cellulase has unusual resistance to trypsinization, shows that it has unusual rock-steady structure. Yet it can be through processing and cracking with hydrogen bromide, and then the fragment of gained can digest with pancreatin or lysyl inscribe PEPC C. The sequence of some peptides that so obtain shows in Table I X.

The 50K-cellulase is a kind of stable enzyme, reaches in larger pH value scope and at high temperature shows the endoglucanase activity, therefore, is applicable to many industrial conditions. When the reaction time of pH7.0 and 60 minutes. Optimum temperature is 65 to 70 ℃, even with reaction time of such length, it still shows the activity (Figure 12) at 50 ℃ viewed 50% in the time of 75 ℃.
Under 60 minute reaction time, pH has the activity of substantial constant just when extremely wide between pH4.4 to 7.0 in the time of 50 ℃, 50% and 30% the when activity pH9 and 10 o'clock equals pH7.0 respectively.

The host strain ALKO 3620 that is used for transforming is egl2 gene defection type (being replaced by the ble gene (Mattern etc., 1988, Drocount etc., 1990) from the different wall bacterium of Hindustan chain). Therefore, these not production of bacterial strain trichoderma cellulase composition EGII and CBHI or EGI.
Sample from the culture supernatant is upward walked electrophoresis at the polyacrylamide plate gel that contains 0.1%SDS at Bio-Rad Mini Protean II electrophoresis system (U.S.). Polyclonal antibody for the preparation of the 20K-cellulase of purifying is used for detecting the protein that produces at the Western trace. In detection, use Promega ' s ProtoBlotThe AP system. Western result shows in Figure 30. Transformant ALKO 3620/pALK 1235/49, ALKO 3620/pALK 1235/40, ALKO 3620/pALK 1231/14 and ALKO 3620/pALK1231/16 ( swimming lane 1,2,4 and 5) produce the protein with the reaction of polyclone 20K-cellulase antiserum. The protein size that transformant produces is big or small identical with the 20K-cellulase (swimming lane 6) of purifying. ALKO 3620 (swimming lane 3) does not produce corresponding protein.
The endoglucanase of pressing embodiment 10 described mensuration transformants is active. When using 2% carboxymethyl cellulose (CMC) when making substrate, reaction temperature rises to 70 ℃, so the endoglucanase activity of ALKO 3620 is heat-inactivated. When using 1% hydroxyl when cellulose is made substrate, before measuring, enzymatic activity carries out hot deactivation. From the sample of growth medium at 0.05M HEPES, dilution and 70 ℃ of insulations 20 minutes in pH 7.0 buffer solutions. Almost completely hot deactivation endoglucanase I (remaining main endoglucanase in ALKO 3620. The activity of the negative transformant of egl1-descends approximately 30% in hot deactivation, shows the cellulosic hot deactivation of 20K-less. The endoglucanase activity provides in Table X X. When HEC was substrate, the 20K-cellulase activity was inferred as through the activity that will obtain after the heat treatment activity before divided by 0.7 heat treatment that obtains.
Table X X. produces the endoglucanase activity of the T.reesei transformant of Melanocarpus albomyces 20K-cellulase.

The endoglucanase activity of T.reesei host strain ALKO 3620 is 70 ℃ of almost completely deactivations. The transformant that produces Melanocarpus albomyces 20K-cellulase produces in a large number relatively heat-staple 20K-cellulase. The endoglucanase level of production of transformant is than several times of 20K-cellulase parent strain ALKO 4237 height.
Embodiment 31
In T.reesei, produce Melanocarpus albomyces
ALKO 423750K cellulase
Make up Trichoderma reesei bacterial strain and be used for Melanocarpus albomyces ALKO 4237 50K-cellulase production. This bacterial strain is produced Melanocarpus 50K-cellulase and can not be produced T.reesei endoglucanase II and the biological hydrolase of cellulose or endoglucanase I. In the structure of the bacterial strain that produces Melanocarpus albomyces 50K-cellulase, use the expression cassette from plasmid pALK 1238 or pALK1240 (Figure 31 and 32) to transform parent Trichoderma reesei strains A LKO 3620. In expression cassette, the 50K cellulase is expressed under strong cbhl promoter. The integration of expression cassette causes replacing parent cbh1 (pALK 1238) or egl1 (pALK 1240) gene. Except replacing the 20K-cellulose enzyme gene with embodiment 22 described 50K-cellulose enzyme genes (1.7kb fragment from the ATG codon). Clone and transform by embodiment 29 is described. Then similar the apparent modification of those skilled in the art is identified the transformant that produces Melanocarpus albomyces 50K-cellulase to embodiment 30. Similar with 30 to embodiment 29, so that the apparent modification preparation of those skilled in the art is produced Melanocarpus albomyces 50K-cellulase B and the transformant with protein of CBD.
Owing to fully described the present invention now, it will be understood by those skilled in the art that and in condition under the prerequisite of the spirit or scope that do not affect the present invention or its any embodiment, to carry out the present invention in the extensive and suitable scope of parameter etc. All lists of references that this paper quotes fully are incorporated herein by reference.
