  • Compositions of variant biocatalysts for preparing enantiopure amino acids
    Publication number: 20110059503
    Abstract: A composition of variant biocatalysts, specifically variants of D-amino acid oxidases, with improved biocatalytic activity towards D-amino acid substrates such as, but not limited to, D-tert-leucine, D-norvaline, D-2-aminobutyrate, D-alanine, D-isoleucine, D-valine, D-methionine, D-hydroxyadamantlyglycine, D-penicillamine, or D-norleucine is disclosed. Further disclosed is a method of preparing enantioselective amino acids using variant D-amino acid oxidases of the present invention.
