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. This family also includes inosicase. The known structures in this family show a common phosphate binding site [1].	Domain
