MUTATIONS IN IRON-SULFUR CLUSTER PROTEINS THAT IMPROVE XYLOSE UTILIZATION

摘要

There is provided an engineered host cells comprising (a) one or more mutations in one or more endogenous genes encoding a protein associated with iron metabolism; and (b) at least one gene encoding a polypeptide having xylose isomerase activity, and methods of their use thereof.
