Methylglyoxal synthase-like domain <p> This domain composes the whole protein of methylglyoxal synthetase and the domain is also found in carbamoyl phosphate synthetase (CPS) where it forms a regulatory domain that binds to the allosteric effector ornithine. The known structures in this domain show a common phosphate binding site [<cite idref="PUB00015023"/>]. </p>
