    Abstract: The present application relates to a strain expressing FrsA protein, and a producing method of ethanol using the same. The FrsA of the present application has high PDC enzyme activity for 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 effectively used in producing ethanol due to the increase in stability when the FrsA mutant is over-expressed together with IIAGlc, compared with when using conventional Zymomonas mobilis-derived PDC.

    Abstract translation: 本申请涉及表达FrsA蛋白的菌株及其使用的乙醇的制造方法。 本申请的FrsA对作为底物的丙酮酸盐具有高PDC酶活性,因此可用于生产乙醇的方法。 此外,与使用常规运动发酵单胞菌来源的PDC时相比,当FrsA突变体与IIAGlc一起过表达时,由于稳定​​性的提高,宿主细胞中具有改善的稳定性的FrsA突变体可以有效地用于生产乙醇。
