1.1.1.76 |
| 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. |
