alcohol dehydrogenase
(1) a primary alcohol + NAD+ = an aldehyde + NADH + H+;;(2) a secondary alcohol + NAD+ = a ketone + NADH + H+
alcohol dehydrogenase (NADP+)
an alcohol + NADP+ = an aldehyde + NADPH + H+
homoserine dehydrogenase
L-homoserine + NAD(P)+ = L-aspartate 4-semialdehyde + NAD(P)H + H+
(R,R)-butanediol dehydrogenase
(R,R)-butane-2,3-diol + NAD+ = (R)-acetoin + NADH + H+
acetoin dehydrogenase
acetoin + NAD+ = diacetyl + NADH + H+
glycerol dehydrogenase
glycerol + NAD+ = glycerone + NADH + H+
propanediol-phosphate dehydrogenase
propane-1,2-diol 1-phosphate + NAD+ = hydroxyacetone phosphate + NADH + H+
glycerol-3-phosphate dehydrogenase (NAD+)
sn-glycerol 3-phosphate + NAD+ = glycerone phosphate + NADH + H+
D-xylulose reductase
xylitol + NAD+ = D-xylulose + NADH + H+
L-xylulose reductase
xylitol + NADP+ = L-xylulose + NADPH + H+
