  • ?-Aminocarboxylic acids, ?-aminocarboxylic acid esters, or recombinant cells which produce lactams thereof
    Patent number: 9012227
    Abstract: The present invention relates to a cell, which has been genetically modified relative to its wild type, so that in comparison with its wild type it is able to produce more ?-aminocarboxylic acids, more ?-aminocarboxylic acid esters or more lactams derived from ?-aminocarboxylic acids, starting from carboxylic acids or carboxylic acid esters. Furthermore, the present invention relates to a method for the production of a genetically modified cell, the cells obtainable by this method, a method for the production of ?-aminocarboxylic acids, of ?-aminocarboxylic acid esters or of lactams derived from ?-aminocarboxylic acids, the ?-aminocarboxylic acids, ?-aminocarboxylic acid esters or lactams derived from ?-aminocarboxylic acids obtainable by this method, a method for the production of polyamides based on ?-aminocarboxylic acids or based on lactams and the polyamides obtainable by this method.

  • Cloning and expression of D-amino acid oxidase from
    Patent number: 7195900
    Abstract: The present invention is directed to a nucleotide sequence encoding D-amino oxidase (D-AAO, EC 1.4.3.3) from Arthrobacter protophormiae. This may be inserted into an expression and used to transform a microbial host. The transformed microbial hosts ecomically produce D-AAO which may be used to oxidize D-amino acids.
