HYPERTHERMOSTABLE ENDOGLUCANASE

摘要

A hyperthermostable endoglucanase, having an endoglucanase catalytic domain including: (A) a polypeptide including an amino acid sequence represented by SEQ ID NO: 1; (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, and having hydrolysis activity against a substrate of carboxymethyl cellulose at least under conditions of a temperature of 110°C and a pH of 5.5; or (C) a polypeptide including an amino acid sequence having at least 55% sequence identity with the amino acid sequence represented by SEQ ID NO: 1, and having hydrolysis activity against a substrate of carboxymethyl cellulose at least under conditions of a temperature of 110°C and a pH of 5.5.
