acetolactate synthase (biosynthetic) M-CSA #289 | Acetolactate synthase is a thiamin pyrophosphate-dependent enzyme that combines two molecules of pyruvate in a stereospecific condensation to yield 2-acetolactate with the release of carbon dioxide. Only the S enantiomer of 2-acetolactate is formed, which is then relayed into the biosynthesis of valine and leucine. Previously it was though that this protein also requires FAD for the protein to fold correctly, although the FAD is not involved in the reaction itself however recent studies (Lonhienne T et al.) have shown that it is involved in reaction by producing the radical that initiates this reaction. It exists in two distinct forms (biosynthetic and catabolic). This entry represents the biosynthetic form that is found in plants, fungi and bacteria. | Defined by 5 residues: GLU:A-129 [auth A-139]PHE:A-191 [auth A-201]GLN:A-192 [auth A-202]LYS:A-241 [auth A-251]MET:B-572 [auth B-582] | EC: 4.1.3.18 (PDB Primary Data) |
