  • Patent number: 7741460
    Abstract: The invention provides methods to increase the production of an amino acid from Corynebacterium species by way of the amplification of amino acid biosynthetic pathway genes in a host cell chromosome. Amplification may be by integration of one or more copies of a gene or genes into a host cell chromosome. One gene that may be incorporated is the gene ORF2, which encodes an unnamed hypothetical protein and which may be obtained from Corynebacterium glutamicum. The invention also provides novel isolated nucleic acid molecules for L-lysine biosynthetic pathway genes of Corynebacterium glutamicum.

  • Publication number: 20100143984
    Abstract: A variant of Corynebacterium shows activity greater than the endogenous activity of aspartate aminotransferase, aspartate kinase, aspartate semialdehyde dehydrogenase, dihydrodipicolinate synthase, dihydropicolinate reductase and diaminopimelate dicarboxylase and additionally pyruvate carboxylase. The variant is used in a method of producing L-lysine.

  • Patent number: 7723097
    Abstract: The invention relates to novel bacterial strains and constructs as well as methods for production of L-amino acids, including but not limited to L-threonine. Such novel bacterial strains may be characterized by, for instance, Escherichia coli strains in which an aspartate semialdehyde dehydrogenase (asd) gene is operably associated with at least one non-native promoter, non-native ribosome binding site, or both.
