Abstract:
The present invention is directed to a method utilizing a microorganism with reduced isocitrate dehydrogenase activity for the production of methionine.
Abstract:
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 suchnucleotide sequences.
Abstract:
The present invention relates to microorganisms, in particular C. glutamicum in which the formation of N 5 , N 10 -methylene-THF is increased. The present invention also relates to the use of such microorganisms for producing methionine.
Abstract:
The present invention pertains to improved microorganisms and methods for the production of methionine and other sulfur containing fine chemicals using the metl gene from Bacillus subtilis or a gene related to metI. In some embodiments of the present invention, the metI gene or another gene is integrated in a fashion that allows for co-production of a water soluble compound such as methionine or other amino acid and a caortenoid compound.
Abstract:
The present invention concerns methods for the production of microorganisms with increased efficiency for methionine synthesis. The present invention also concerns microorganisms with increased efficiency for methionine synthesis. Furthermore, the present invention concerns methods for determining the optimal metabolic flux for organisms with respect to methionine synthesis.

Abstract:
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- l,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.
