Endoxylanase mutant, enzyme composition for biomass degradation, and method for producing sugar solution

摘要

Provided are endoxylanase variants with improved thermal stability. One or more amino acid residues selected from positions corresponding to position 35, position 44, position 62, position 63, position 101, and position 102 of at least the amino acid sequence of SEQ ID NO: 1 in the amino acid sequence of filamentous fungal endoxylanase An endoxylanase variant comprising an amino acid sequence in which the group is substituted and having endoxylanase activity.
