This invention relates generally to enzymes, polynucleotides encoding the enzymes, the use of such polynucleotides and polypeptides and more specifically to enzymes having transferase activity, e.g., transaminase activity, e.g., d-amino-acid transferase activity, and/or oxidoreductase activity, e.g., dehydrogenase activity, e.g., d-amino-acid dehydrogenase activity, and/or catalyze the transfer of a chemical group, catalyze transamination, catalyze the reaction: D-alanine+2-oxoglutarate<=>pyruvate+D-glutamate, and/or catalyze an oxidation-reduction reaction, catalyze the removal of hydrogen atoms, and/or catalyze the reaction: D-amino acid+H
