Chains	Enzyme Name	Description	Catalytic Residues
A	glutamate racemase M-CSA #1	Glutamate racemase is responsible for the synthesis of D-glutamate, an essential building block of peptidoglycan, found in bacterial cell walls where it provides structural integrity. Due to its uniqueness to bacteria, peptidoglycan, and enzymes involved in its biosynthesis, are targets for designing new antibacterial drugs. Peptidoglycan is formed from a repeating unit of a disaccharide, N-acetylglucosamine and N-acetylmuramic acid to which a small group of amino acids (L-alanine, D-alanine, D-glutamate and either lysine or diaminopimelic acid) are covalently attached. The presence of D-amino acids protects the cell wall from proteases which can only recognise the L-isomer.
