DNA SEQUENCE INCLUDING A CODATING GENE FOR XYLOSE REDUCTASE OR XYLOSE REDUCTASE AND XYLITOL DEHYDROGENASE.

摘要

THE INVENTION REFERS TO A DNA SEQUENCE THAT HAS A STRUCTURAL GENE THAT CODES XYLOSE REDUCTASE AND / OR XYLITOL DEHYDROGENASE AND THAT IS ABLE TO EXPRESS THESE POLYPEPTIDES IN A MICROORGANISM. THE INVENTION FURTHER REFERS TO A COMBINATION OF DNA SEQUENCES, A VECTOR, A MICROORGANISM, A METHOD FOR PRODUCING XYLOSA REDUCTASE AND / OR XYLITOL DEHYDROGENASE. THE MICROORGANISMS, WHICH EXPRESS THE STRUCTURAL GENES UNDERTAKEN BY THE INVESTIGATING DNA SEQUENCES, CAN BE USED TO PRODUCE ETHANOL FROM XILULOSA, TO PRODUCE BIOMASS AND TO RECOVER HIGH NADP + FROM NADPH. THE PREFERRED MICROORGANISMS ARE S.CEREVISIAL AND SCHIZOSACCHAROMYCAS POMBE.
