Accepted name: 3-methylbutanal reductase
Reaction: 3-methylbutanol + NAD(P)+ = 3-methylbutanal + NAD(P)H + H+
Systematic name: 3-methylbutanol:NAD(P)+ oxidoreductase
Comments: The enzyme purified from Saccharomyces cerevisiae catalyses the reduction of a number of straight-chain and branched aldehydes, as well as some aromatic aldehydes.
