Patent number: 8048648Abstract: 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.Type: GrantFiled: January 11, 2008Date of Patent: November 1, 2011Assignee: CJ Cheil Jedang CorporationInventors: Hye Won Kim, Hyejin Choi, Ji-Hye Lee, Soo Youn Hwang

Patent number: 7378267Abstract: A method for producing L-threonine using a microorganism is provided. In the method, the threonine dehydratase (tdc) gene existing in the genomic DNA of the microorganism is partially deactivated using a recombination technique. For a microorganism strain with enhanced activity of threonine operon-containing enzymes and the phosphoenolpyruvate carboxylase (ppc) gene, the tdc gene engaged in one of the four threonine metabolic pathways is specifically deactivated, thereby markedly increasing the yield of L-threonine.Type: GrantFiled: May 16, 2002Date of Patent: May 27, 2008Assignee: Cheil Jedang CorporationInventors: Jae Yong Park, Byoung Choon Lee, Dae Cheol Kim, Jin Ho Lee, Jae Yong Cho, Young Hoon Park
