    摘要： Disclosed is a method of producing 5′-guanosine monophosphate using a novel microorganism which has a malate dehydrogenase activity higher than that of a wild-type, thereby showing improved ATP productivity. Also, a novel microorganism is disclosed. The method comprises: culturing the corynebacteria strain which is enhanced in malate dehydrogenase activity over the endogenous activity, thus producing ATP in high yield; producing XMP in the culture; adding to the culture an enzyme or microorganism having XMP amination activity; and obtaining GMP from the culture.

    摘要： The present invention relates to an L-arginine producing mutant strain, and a method for fabricating the same. In particular, the present invention relates to a polynucleotide comprising an argD2 gene (Ncgl2355) that is a putative gene of acetylornithine aminotransferase involved in arginine biosynthesis of Corynebacterium glutamicum, a polypeptide encoded by the polynucleotide, a recombinant vector comprising the polynucleotide, a transformant capable of producing L-arginine in a high yield, which is prepared by introducing the recombinant vector into an L-arginine producing host microorganism to overexpress the argD2 gene, and a method for producing L-arginine by culturing the transformant. The transformant of the present invention overexpresses the argD2 gene to produce L-arginine in a high yield, thereby being used in medicinal and pharmaceutical industries.
