THERMOSTABLE SS-XYLOSIDASE BELONGING TO GH FAMILY 3

摘要

A thermostable ²-xylosidase, having a ²-xylosidase catalytic domain including: (A) a polypeptide including the amino acid sequence represented by SEQ ID NO: 1, 3 or 5, (B) a polypeptide including an amino acid sequence in which at least one amino acid has been deleted, substituted, or added in the amino acid sequence represented by SEQ ID NO: 1, 3 or 5, and having hydrolysis activity against a substrate of p-nitrophenyl-²-D-xylopyranoside at least under conditions of 80°C and pH 4.0, or (C) a polypeptide including an amino acid sequence having 80% or greater sequence identity with the amino acid sequence represented by SEQ ID NO: 1, 3 or 5, and having hydrolysis activity against a substrate of p-nitrophenyl-²-D-xylopyranoside at least under conditions of 80°C and pH 4.0.
