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.

The present invention relates to microorganisms, in particular C. glutamicum in which the formation of N5,N10-methylene-THF is increased.The present invention also relates to the use of such microorganisms for producing methionine.
摘要:
The present invention relates to nulceotide sequences encoding enzymatically active cobalamin-methionine synthase and functional fragments thereof being modified in comparison to the respective wild-type enzyme such that said enzymes show reduced product inhibition by methionine. The present invention also relates to polypeptides being encoded by such nucleotide sequences and host cells comprising such nucleotide sequences. Furthermore, the present invention relates to methods for producing methionine in host organisms by making use of such nucleotide sequences.
摘要:
The present invention is directed to a method utilizing a microorganism with reduced isocitrate dehydrogenase activity for the production of fine chemicals. Said fine chemicals may be amino acids, monomers for polymer synthesis, sugars, lipids, oils, fatty acids or vitamins and are preferably amino acids of the aspartate family, especially methionine or lysine, or derivatives of said amino acids, especially cadaverine. Furthermore, the present invention relates to a recombinant microorganism having a reduced isocitrate dehydrogenase activity in comparison to the initial microorganism and the use of such microorganisms in producing fine chemicals such as aspartate family amino acids and their derivatives.
