  • 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.

  • Patent number: 9550980
    Abstract: Healthcare costs are a significant worldwide, with many patients being denied medications because of their high prices. One approach to addressing this problem involves the biosynthesis of chiral drug intermediates, an environmentally friendly solution that can be used to generate pharmaceuticals at much lower costs than conventional techniques. In this context, embodiments of the invention comprise methods and materials designed to allow microorganisms to biosynthesize the nonnatural amino acid L-homoalanine. As is known in the art, L-homoalanine is a chiral precursor of a variety of pharmaceutically valuable compounds including the anticonvulsant medications levetiracetam (sold under the trade name Keppra®) and brivaracetam, as well as ethambutol, a bacteriostatic antimycobacterial drug used to treat tuberculosis. Consequently, embodiments of the invention can be used in low cost, environmentally friendly processes to generate these and other valuable compounds.
