| - | '''Aspartate-semialdehyde dehydrogenase''' (ASADH) is an enzyme which is part of the biosynthesis of amino acids. It catalyzes the conversion of L-aspartate 4-semialdehyde (ASA) + phosphate + NADP to L-4-aspartyl phosphate + NADPH + H+. The images at the left and at the right correspond to one representative ASADH, ''i.e.'' the crystal structure of Aspartate-semialdehyde dehydrogenase from ''Vibrio cholerae'' ([[1mc4]]). | + | '''Aspartate-semialdehyde dehydrogenase''' (ASADH) is an enzyme which is part of the biosynthesis of amino acids in bacteria, plants and fungi. It catalyzes the conversion of L-aspartate 4-semialdehyde (ASA) + phosphate + NADP to L-4-aspartyl phosphate + NADPH + H+. |

| - | <br /> | + | ASADH contains 2 domains. The N terminal domain contains the <scene name='45/452498/Cv/7'>active site</scene> and the <scene name='45/452498/Cv/9'>NADP-binding site</scene>. The active site contains a <scene name='45/452498/Cv/10'>cysteine residue</scene> (C134 in ''Vibrio Cholerae'') which binds to inhibitors. The C terminal contains the homodimer intersubunit contacts. <ref>PMID:12493825</ref> |
