The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.
Mass balance status: Marked as unbalanced.
Enzyme Commission Primary Name: alcohol dehydrogenase (NADP+)
Enzyme Commission Synonyms: aldehyde reductase (NADPH2), NADP-alcohol dehydrogenase, NADP+-aldehyde reductase, NADP+-dependent aldehyde reductase, NADPH-aldehyde reductase, NADPH-dependent aldehyde reductase, nonspecific succinic semialdehyde reductase, ALR 1, low-Km aldehyde reductase, high-Km aldehyde reductase, alcohol dehydrogenase (NADP)
Enzyme Commission Summary:
A zinc protein. Some members of this group oxidize only primary alcohols; others act also on secondary alcohols. May be identical with EC 22.214.171.124, glucuronate reductase, EC 126.96.36.199, mevaldate reductase (NADPH) and EC 188.8.131.52, lactaldehyde reductase (NADPH). Re-specific with respect to NADPH.
Instance reaction of [an aldehyde + NADP+ + H2O → a carboxylate + NADPH + 2 H+] (184.108.40.206):
i3: acetaldehyde + NADP+ + H2O → acetate + NADPH + 2 H+ (220.127.116.11)
Instance reactions of [an alcohol + NADP+ = an aldehyde + NADPH + H+] (18.104.22.168):
i1: (S)-propane-1,2-diol + NADP+ = (S)-lactaldehyde + NADPH + H+ (1.1.1.-)
i2: (R)-propane-1,2-diol + NADP+ = (R)-lactaldehyde + NADPH + H+ (1.1.1.-)
