(S,S)-butanediol dehydrogenase

Class of enzymes (S,S)-butanediol dehydrogenase 1.1.1.76 37250-14-9 0047512 3a28.jpg In enzymology, (S,S)-butanediol dehydrogenase (1.1.1.76) is an enzyme that catalyzes the chemical reaction 60% class=skin-invert-image|frameless (S,S)-butane-2,3-diol + NAD+ reversible H+ H+ class=skin-invert-image|frameless (S)-acetoin + NADH The two substrates of this enzyme are (S,S)-butane-2,3-diol and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are (S)-acetoin, reduced NADH, and a proton.1.1.1.76 Taylor MB, Juni E Stereoisomeric specificities of 2,3-butanediol dehydrogenases Biochimica et Biophysica Acta 39 3 448–57 April 1960 13837186 10.1016/0006-3002(60)90197-9 This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (S,S)-butane-2,3-diol:NAD+ oxidoreductase. Other names in common use include L-butanediol dehydrogenase, L-BDH, and L(+)-2,3-butanediol dehydrogenase (L-acetoin forming). This enzyme participates in butanoic acid metabolism.
