Abstract
An endoxylanase mutant has improved thermal stability. The endoxylanase mutant having endoxylanase activity includes an amino acid sequence at least including substitution of an amino acid residue at one or more positions selected from positions corresponding to position 35, position 44, position 62, position 63, position 101, and position 102 of an amino acid sequence of SEQ ID NO: 1 in an amino acid sequence of endoxylanase derived from a filamentous fungus.
