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., damino-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+H2O+acceptor a 2-oxo acid+NH3+reduced acceptor. Thus, the invention provides enzymes, compositions, methods for production of pharmaceutical compositions, pharmaceutical intermediates, antibiotics, sweeteners, peptide enzymes, peptide hormones, fuel and fuel additive compositions, foods and food additives, beverage and beverage additives, feeds and feed additives, drugs and drug additives, dietary supplements, textiles, wood, paper, pulp, and detergents comprising the polypeptides or polynucleotides in accordance with the invention.
