  • Mutant xylose-metabolizing enzyme and use thereof
    Patent number: 10626404
    Abstract: The present invention provides information on a mutant xylose isomerase gene and a mutant protein with which it is possible to impart high xylose metabolic capacity to budding yeast. Also provided is a yeast strain having the mutant xylose isomerase gene. Additionally provided is an efficient method for producing a useful substance using the yeast strain. The present invention provides mutant Clostridium-phytofermentans-derived xylose isomerase (CpXI) having high xylose metabolic activity, the CpXI comprising an amino acid sequence corresponding to an amino acid sequence in which the number 63 threonine of SEQ ID NO: 11 of CpXI is substituted by isoleucine, leucine, glycine, or histidine and/or the number 162 valine is substituted by alanine.
    Type: Grant
