  • Patent number: 9567576
    Abstract: The present application relates to a strain expressing the FrsA protein, and a method for producing ethanol using the same. The FrsA of the present application has a high PDC enzyme activity for a pyruvate, which is a substrate, and thus can be used in a process for producing ethanol. In addition, an FrsA mutant having improved stability in a host cell can be more effective in producing ethanol due to the increase in stability when the FrsA mutant is overexpressed together with IIAGlc, compared with when using conventional Zymomonas mobilis-derived PDC.
