dat; D-alanine aminotransferase. 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 [KO:K00824] [EC:2.6.1.21]
ycjG; L-Ala-D/L-Glu epimerase; also epimerizes some other Ala-X dipeptides, YcjG has a role in the recycling of the murein peptide.Muconate [KO:K19802] [EC:5.1.1.205.1.1.25]
