  • Publication number: 20130023016
    Abstract: The present invention relates to a polynucleotide that is active to an acetyl glutamate synthase and acetyl ornithinase which are associated with ornithine or arginine biosynthesis from Corynebacterium glutamicum. The present invention also relates to a polypeptide encoded by said polynucleotide, a recombinant vector comprising said polynucleotide, to a transformant obtained by introducing said recombinant vector to a host microorganism for producing L-ornithine or L-arginine, and transforming the recombinant vector, and to a method for producing L-ornithine or L-arginine by culturing said transformant. The activity of the transformant of the present invention to an acetyl glutamate synthase and acetyl ornithinase is increased as compared to an intrinsic activity, and thus L-ornithine or L-arginine can be produced, at a high yield rate, from the transformant of the present invention.
