HYPERTHERMOSTABLE ENDOGLUCANASE BELONGING TO GH FAMILY 12

摘要

A hyperthermostable endoglucanase including an endoglucanase catalytic domain, the 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 is deleted, substituted, or added in the amino acid sequence represented by SEQ ID NO: 1, and having hydrolytic activity using p-nitrophenyl-²-D-cellobioside as a substrate at least under conditions of a temperature of 100°C and a pH of 5.5; or
(C) a polypeptide including an amino acid sequence having at least 70% sequence identity with the amino acid sequence represented by SEQ ID NO: 1, and having hydrolytic activity using p-nitrophenyl-²-D-cellobioside as a substrate at least under conditions of a temperature of 100°C and a pH of 5.5.
