  • Xylose reductase mutants and uses thereof
    Patent number: 8822661
    Abstract: Engineered mutant xylose reductases demonstrate higher preference to xylose than arabinose. Amino acid mutations were engineered in to native xylose reductase from Neurospora crassa. Mutant xylose reductases are useful in the production of xylitol and ethanol.
