CORYNEBACTERIUM GLUTAMICUM VARIETY PRODUCING L-ARGININE AND METHOD FOR FABRICATING THE SAME

摘要

An L-arginine producing microorganism is provided to produce the L-arginine with high yield by over-expressing an argD2 gene in a host microorganism, thereby being usefully used for human medicinal and pharmaceutical industries. An L-arginine producing microorganism is characterized in that it is transformed by recombinant vector including a polynucleotide encoding an argD2(NCBI access no. Ncg12355) polypeptide having an amino acid sequence described as SEQ ID : NO. 1, wherein the polynucleotide is described as SEQ ID : NO. 2 and the microorganism is Corynebacterium sp. and is deposited as a deposition no. KCCM10820P or KCCM10821P. A method for preparing L-arginine comprises a step of culturing the L-arginine producing microorganism.
