(S,S)-butanediol dehydrogenase

Template:Short description Template:Infobox enzyme In enzymology, a (S,S)-butanediol dehydrogenase (Template:EC number) is an enzyme that catalyzes the chemical reaction

(S,S)-butane-2,3-diol + NADTemplate:Sup $\rightleftharpoons$ acetoin + NADH + HTemplate:Sup

Thus, the two substrates of this enzyme are (S,S)-butane-2,3-diol and [[nicotinamide adenine dinucleotide|NADTemplate:Sup]], whereas its 3 products are acetoin, NADH, and [[hydrogen ion|HTemplate:Sup]].

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NADTemplate:Sup or NADPTemplate:Sup as acceptor. The systematic name of this enzyme class is (S,S)-butane-2,3-diol:NADTemplate:Sup oxidoreductase. Other names in common use include L-butanediol dehydrogenase, L-BDH, and L(Template:Sup)-2,3-butanediol dehydrogenase (L-acetoin forming). This enzyme participates in butanoic acid metabolism.
