摘要:
The present invention features methods of increasing the production of a fine chemical, e.g., lysine from a microorganism, e.g., Corynebacterium by way of deregulating an enzyme encoding gene, i.e., fructose-1,6-bisphosphatase. In a preferred embodiment, the invention provides methods of increasing the production of lysine in Corynebacterium glutamicum by way of increasing the expression of fructose-1,6-bisphosphatase activity. The invention also provides a novel process for the production of lysine by way of regulating carbon flux towards oxaloacetate (OAA). In a preferred embodiment, the invention provides methods for the production of lysine by way of utilizing fructose or sucrose as a carbon source.

Isolated nucleic acid molecules, designated MR nucleic acid molecules, which encode novel MR proteins from Corynebacterium glutamicum are described which are involved in biosynthesis of a fine chemical, e.g., methionine biosynthesis. The invention also provides antisense nucleic acid molecules, recombinant expression vectors containing MR nucleic acid molecules, and host cells into which the expression vectors have been introduced. The invention still further provides methods of producing methionine from microorganisms, e.g., C. glutamicum, which involve culturing recombinant microorganisms which overexpress or underexpress at least one MR molecule of the invention under conditions such that methionine is produced. Also featured are methods of producing a fine chemical, e.g., methionine, which involve culturing recombinant microorganisms having selected MR genes deleted or mutated under conditions such that the fine chemical, e.g., methionine, is produced.
