CPS I and II are composed of 2 subunits. The large subunit contain active sites which bind nucleotides and other effectors. The small subunit catalyzes the hydrolysis of glutamine to glutamate and NH3. The <scene name='49/493669/Cv/2'>small subunit active site contains an active Cys residue</scene>. CPS I contains a methylglyoxal synthetase (MGS) domain which binds ornithine.
