Enzyme Information

1.1.1.9
D-xylulose reductase.
based on mapping to UniProt Q00796
Xylitol + NAD(+) = D-xylulose + NADH.
-!- Also acts as an L-erythrulose reductase.
1.1.1.56
Ribitol 2-dehydrogenase.
based on mapping to UniProt Q00796
Ribitol + NAD(+) = D-ribulose + NADH.
1.1.1.4
(R,R)-butanediol dehydrogenase.
based on mapping to UniProt Q00796
(R,R)-butane-2,3-diol + NAD(+) = (R)-acetoin + NADH.
-!- Also converts diacetyl into acetoin with NADH as reductant.
1.1.1.-
With NAD(+) or NADP(+) as acceptor.
based on mapping to UniProt Q00796
1.1.1.14
L-iditol 2-dehydrogenase.
based on mapping to UniProt Q00796
L-iditol + NAD(+) = L-sorbose + NADH.
-!- This enzyme is widely distributed and has been described in archaea, bacteria, yeast, plants and animals. -!- It acts on a number of sugar alcohols, including (but not limited to) L-iditol, D-glucitol, D-xylitol, and D-galactitol. -!- Enzymes from different organisms or tissues display different substrate specificity. -!- The enzyme is specific to NAD(+) and can not use NADP(+).
