Method: X-ray diffraction, Resolution 2Å Ligands: ACT, PLP Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function DAAA_BACYM Acts on the D-isomers of alanine, leucine, aspartate, glutamate, aminobutyrate, norvaline and asparagine. The enzyme transfers an amino group from a substrate D-amino acid to the pyridoxal phosphate cofactor to form pyridoxamine and an alpha-keto acid in the first half-reaction. The second-half reaction is the reverse of the first, transferring the amino group from the pyridoxamine to a second alpha-keto acid to form the product D-amino acid via a ping-pong mechanism. This is an important process in the formation of D-alanine and D-glutamate, which are essential bacterial cell wall components. Evolutionary Conservation Check, as determined by ConSurfDB.
