  • Patent number: 7267967
    Abstract: A pyruvate carboxylase gene having SEQ ID NO:1 as well as an amino acid sequence having SEQ ID NO:2 expressed by the pyruvate carboxylate gene are disclosed. Also disclosed is a method for microbial production of amino acids of the aspartate and/or glutamate family in which the pyruvate carboxylase activity is increased by genetically changing the pyruvate carboxylase gene having SEQ ID NO:1 through expression of a microorganism which produces the corresponding amino acid having SEQ ID NO:2.
    Type: Grant
    Filed: September 30, 1998
    Date of Patent: September 11, 2007
    Assignee: Forschungszentrum Julich GmbH
    Inventors: Bernd Eikmanns, Petra Peters-Wendisch, Hermann Sahm
  • Publication number: 20070202571
    Abstract: A method is disclosed for microbially producing L-amino acids of aspartate and/or glutamate families which comprises the step of: culturing a strain of Escherichia coli that produces said L-amino acids in a medium suitable for the production of an L-amino acid, whereby said Escherichia coli strain is transformed with a gene construct comprising a polynucleotide encoding an enzyme with pyruvate carboxylase activity.

  • Publication number: 20020142405
    Abstract: The invention relates to nucleotide sequences coding for the accDA gene and to a process for the preparation of L-amino acids, especially L-lysine, by fermentation using corynebacteria in which the accDA gene is amplified.
    Type: Application

  • Patent number: 6379934
    Abstract: The invention provides a process for the fermentative preparation of L-amino acids using coryneform bacteria, in which the subunit carrying the biotin-carboxyl carrier protein domain and the biotin-carboxylase domain of the nucleotide sequence encoding the enzyme acetyl-CoA carboxylase (accBC gene) is amplified, in particular is overexpressed.
