Patent number: 9267161Abstract: The present invention relates to Corynebacterium sp. that is transformed with an Escherichia sp.-derived fructokinase gene to express fructokinase showing a sufficient activity of converting fructose into fructose-6-phosphate, thereby preventing unnecessary energy consumption, and a method for producing L-amino acids using the strain. The transformed Corynebacterium sp. of the present invention is able to express fructokinase from the Escherichia-derived fructokinase gene to prevent unnecessary energy consumption during fructose metabolism, leading to more cost-effective production of L-amino acids. Therefore, it can be widely used for the effective production of L-amino acids.Type: GrantFiled: April 2, 2012Date of Patent: February 23, 2016Assignee: CJ CHEILJEDANG CORPORATIONInventors: Hyun Won Bae, Hyung Joon Kim, Jun Ok Moon, Jae Woo Jang, Jong Chul Kim, Tae Han Kim, Jin Suck Sung, Kyung Han Lee, Dae Cheol Kim, Hyo Jin Kim, Hyun Ae Bae, Sang Jo Lim
