In enzymology, (S,S)-butanediol dehydrogenase (EC 1.1.1.76) is an enzyme that catalyzes the chemical reaction

+ NAD+
 
 
 
H+
(S,S)-butanediol dehydrogenase
 
H+
 
+ 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] [2]

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.
