Accepted name: (S,S)-butanediol dehydrogenase
Reaction: (2S,3S)-butane-2,3-diol + NAD+ = (S)-acetoin + NADH + H+
Other name(s): L-butanediol dehydrogenase; L-BDH; L(+)-2,3-butanediol dehydrogenase (L-acetoin forming); (S)-acetoin reductase [(S,S)-butane-2,3-diol forming]
Systematic name: (S,S)-butane-2,3-diol:NAD+ oxidoreductase
Comments: This enzyme catalyses the reversible reduction of (S)-acetoin to (S,S)-butane-2,3-diol. It can also catalyse the irreversible reduction of diacetyl to (S)-acetoin.
