aspartate racemase (CC-type)  M-CSA #335

Although L-enantiomers of amino acids are predominant in living organisms, D-enantiomers are distributed widely in bacteria, archaea and mammalian tissue. D-aspartate (D-Asp) is one of the most abundant D-enantiomers.
Aspartate racemase (AspR) is a pyridoxal 5'-phosphate (PLP)-independent amino acid racemase that catalyses the interconversion of L-Asp and D-Asp.
