  • Rhodococcus nitrile hydratase
    Patent number: 7288402
    Abstract: The invention relates to a Rhodococcus polynucleotide cluster which contains nucleotide sequences which encode polypeptides having the activity of a nitrile hydratase, of an auxiliary protein P15K which activates this enzyme and of a cobalt transporter, to transformed microorganisms in which the nucleotide sequences encoding these proteins are present in increased quantity, and to the use of the transformed microorganisms for preparing amides from nitriles.
    Type: Grant
    Filed: March 18, 2005
    Date of Patent: October 30, 2007
    Assignee: Degussa AG
    Inventors: Steffen Osswald, Stefan Verseck, Uta Deiting, Christoph Weckbecker, Klaus Huthmacher, Michael Binder, Maria-Regina Kula, Konrad Odendahl
  • Method for the preparation of L-amino acids from D-amino acids
    Patent number: 7217544
    Abstract: The invention relates to recombinant microorganisms which, in comparison to the starting organism, have a higher concentration or activity of a D-amino acid oxidase, of an L-amino acid dehydrogenase, of an NADH cosubstrate regenerating enzyme and, if necessary, of a catalase. The invention also includes methods for preparing L-amino acids from D-amino acids using of these microorganisms.
