additional information | the enzme catalyze asymmetric CC bond formation from pyruvate (as donor) and an aldehyde (as acceptor). Thiamine diphosphate-dependent enzymes catalyze the formation of acetoin (3-hydroxybutan-2-one) through one of three different pathways: homocoupling of pyruvate, homocoupling of acetaldehyde, or cross-coupling of acetaldehyde (as acceptor) and pyruvate (as donor). Thiamine diphosphate-dependent cyclohexane-1,2-dione hydrolase is able to form (S)-acetoin with particularly high enantioselectivity (up to 95%ee) by all three pathways. An unprecedented non-acetolactate pathway for the homocoupling of pyruvate explains the high enantioselectivity in the CDH-catalyzed formation of (S)-acetoin, enzymatic formation of highly enantioenriched acetoin from two molecules of pyruvate occurs without the release of acetaldehyde or acetolactate, mechanism, overview | Azoarcus sp. | ? | - |
