Definitions
- the present application relates to variant polypeptides having Xylanase activity and uses thereof.
- Xylanase (EC 3.2.1.8) is a hydrolase that randomly degrades the ⁇ -1,4 backbone of xylan, a plant cell wall component. Xylanase is mainly used to break down biomass in animal feed, bakery, pulp bleaching, etc. (Beg QK, Kapoor M, Mahajan L, Hoondal GS. Microbial xylanases and their industrial applications: a review Appl Microbiol Biotechnol. 2001 Aug;56(3-4):326-38.doi:10.1007/s002530100704.PMID:11548999.)
- One object of the present application is to provide a variant polypeptide having xylanase activity.
- Another object of the present application is to provide a composition comprising the variant polypeptide.
- Another object of the present application is to provide a use of the variant polypeptide or the composition for reaction with a xylan-containing material.
- Another object of the present application is a xylan-containing material, comprising contacting the variant polypeptide, a host cell expressing the variant polypeptide, and/or a composition comprising the variant polypeptide with a xylan-containing material decomposition method; and/or to provide a method for preparing xylooligosaccharide and/or xylose.
- Another object of the present application is a polynucleotide encoding the variant polypeptide; a nucleic acid construct comprising the polynucleotide; a vector comprising the polynucleotide or nucleic acid construct; And/or to provide a host cell comprising the polynucleotide, nucleic acid construct or vector.
- Another object of the present application is to provide a method for producing the variant polypeptide.
- the variant polypeptide having xylanase activity of the present application may be usefully used in various industrial fields.
- One aspect of the present application is a variant polypeptide having xylanase activity.
- the variant polypeptide is a polypeptide having at least 70% and less than 100% sequence identity to SEQ ID NO: 1; and/or
- the variant polypeptide is a polypeptide encoded by a polynucleotide having at least 70% and less than 100% sequence identity with the sequence encoding the mature polypeptide of SEQ ID NO: 1; and/or
- the variant polypeptide comprises (a) the mature polypeptide coding sequence of SEQ ID NO: 1, (b) cDNA thereof, or (c) the full-length complement sequence of (a) or (b) and low stringency a polypeptide encoded by a polynucleotide that hybridizes under high stringency conditions, medium stringency conditions, medium stringency conditions, high stringency conditions, or very high stringency conditions; and/or
- said variant polypeptide is a functional fragment of i), ii) or iii) polypeptide having xylanase activity;
- the variant polypeptide comprises any one of the modifications selected from the following:
- the position number is a position corresponding to the position of the polypeptide of SEQ ID NO: 1.
- amino acid 3 is arginine (R); amino acid 5 is serine (S); amino acid 20 is phenylalanine (F); amino acid 34 is serine (S); amino acid number 36 is threonine (T); and/or amino acid 41 may be alanine (A).
- the variant polypeptide may include a modification of an amino acid at a position selected from the following:
- the position number is a position corresponding to the position of the polypeptide of SEQ ID NO: 1.
- the modification of each position of the variant polypeptide may include modification of any one or more of the following i) to vi):
- the position number is a position corresponding to the position of the polypeptide of SEQ ID NO: 1.
- the variant polypeptide may include any one or more modifications selected from the following:

- Orpinomyces Orpinomyces (Orpinomyces) sp.
- the xylanase mutant (hereinafter, described as Op Xyn, SEQ ID NO: 1) gene (SEQ ID NO: 2) from the genomic DNA of the PC-2 strain was amplified and cloned into the pHCE vector (Takara) It was used as a template.
- the xylanase mutant was prepared by PCR using a template, a primer, and a PCR premix (iNtRON, cat no. 25185). PCR was performed using an Eppendorf Mastercycler Nexus GX2, and reaction conditions were as follows.
- the seven types of mutants made were ligated using the In-Fusion HD cloning kit (Takara, Cat. No. 639650), and then, the sequence mutation was confirmed by sequencing after transformation into the E. coli Dh5 ⁇ strain. .
- the E. coli Dh5 ⁇ strain each transformed with the mutant prepared in Example 1 and the Op Xyn gene, was inoculated into a sterile LB medium (BD Difco), cultured at 37° C. and 180 rpm for 24 hours, and then centrifuged through centrifugation. was recovered. 20 ml of lysis buffer (lysis buffer: 50 mM Tris-HCl pH 8.0, 100 mM NaCl, 10 mM imidazole) was added to the recovered cells for redispersion, and then the crude enzyme solution was obtained through sonication and centrifugation. The crude enzyme solution was flowed to Ni-NTA resin (Qiagen, Cat no.
- the concentration of the enzyme was obtained by mixing 4 ⁇ l of diluted enzyme solution + 196 ⁇ l of Bradford solution (Quick StartTM Bradford 1x Dye Reagent, #5000205) and then measuring absorbance at 595 nm.
- the enzyme titer was obtained by mixing 4 ⁇ l of 1M pH 6.5 phosphate buffer in 96 ⁇ l of 1% xylan from beachwood, Megazyme, P-XYLNBE-10G, and then mixing 100 ⁇ l of the diluted enzyme solution, 37°C. The reaction was carried out for 15 minutes and measured. The reaction was stopped by mixing 300 ⁇ l of DNS solution with the reaction solution, boiled for 7 minutes to develop color, and then cooled in ice water. Herein, the absorbance at 550 nm of the solution mixed with 500 ⁇ l distilled water was measured, and the titer was measured using a standard curve made of xylose (xylose, Sigma-Aldrich, X1500).
- the DNS solution preparation method is as follows. In a beaker containing 500 ml of distilled water, 6.3 g of 3,5-dinitrosalicylic acid (3,5-dinitrosalicylic acid, samchun, D1267) was added, the temperature was adjusted to 50 °C, and 21 g of sodium hydroxide (Daejung, 7571) -4400) was added.
- the purified enzyme was diluted to a concentration of 0.5 mg/ml, incubated in a water bath at 70° C. for 10 minutes, and then the residual titer was measured.
