摘要:
The present invention relates to methods for the production of microorganisms with increased efficiency for methionine synthesis, microorganisms with increased efficiency for methionine synthesis, and methods for determining the optimal metabolic flux for organisms with respect to methionine synthesis.
摘要:
The present invention relates to nucleotide sequences encoding enzymatically active cobalamin-methionine synthase and functional fragments thereof that are 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 relates to microorganisms and processes for the efficient preparation of L-amino acids such as L-methionine. In particular, the present invention relates to microorganisms and processes in which the formation and/or accumulation of homolanthionine in the methionine pathway is reduced and/or prevented.
摘要:
The present invention relates to multiple promoters and to expression units comprising them; to the use thereof for regulating transcription and expression of genes; to expression cassettes which comprise multiple promoters or expression units of this kind; to vectors which comprise such expression cassettes; to genetically modified microorganisms which comprise vectors and/or expression units of this kind; and to processes for preparing biosynthetic products by culturing said genetically modified microorganisms.
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 relates to microorganisms and processes for the efficient preparation of L-methionine. In particular, the present invention relates to processes in which the amount of serine available for the metabolism of the microorganism is increased.
摘要:
The present invention relates to mutated nucleic acids and proteins of the metabolic pathway of fine chemicals, to processes for preparing genetically modified producer organisms, to processes for preparing fine chemicals by culturing genetically modified organisms, and to genetically modified organisms themselves.
摘要:
The present invention relates to the use of nucleic acid sequences for regulating the transcription and expression of genes, the novel promoters and expression units themselves, methods for altering or causing the transcription rate and/or expression rate of genes, expression cassettes comprising the expression units, genetically modified microorganisms with altered or caused transcription rate and/or expression rate, and methods for preparing biosynthetic products by cultivating the genetically modified microorganisms.
