The present invention relates to a microorganisms of the genusproducing 5'-inosinic acid, in which the expression of genes encoding purine biosynthesis related enzymes is increased higher than the intrinsic expression, and to a method for producing 5&#x2032;-inosinic acid, comprising culturing the microorganisms of the genuswith improved 5&#x2032;-inosinic acid productivity.

[object Object]

A microorganism of the genushaving the ability to produce inosine in which the inosine catabolic pathway is blocked and that has a leaky adenine auxotrophic phenotype and further has a leaky guanine auxotrophic phenotype and a method of producing inosine, the method including culturing the microorganism of the genusare disclosed.

The present invention relates to a microorganism having an enhanced L-valine productivity and a method for producing L-valine using the same. More particularly, the present invention relates to amutant strain that has resistance to L-valine and derivatives thereof so as to have an enhanced L-valine productivity, and a method for producing L-valine using the same.

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, 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.
