Abstract:
This invention is intended to improve the ethanol fermentation ability of a yeast strain having xylose-metabolizing ability with the use of a mutant gene encoding a mutant protein comprising a consensus sequence comprising a substitution of amino acid in the 30th position in SEQ ID NO: 1, amino acid in the 43rd position in SEQ ID NO: 4, and amino acid in the 31st position in SEQ ID NO: 7 with other amino acid residues.
