3-methylbutanal reductase

In enzymology, a 3-methylbutanal reductase () is an enzyme that catalyzes the chemical reaction
The three substrates of this enzyme are 3-methylbutan-1-ol (isoamyl alcohol), NAD+, and NADP+, whereas its four products are 3-methylbutanal, NADH, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 3-methylbutanol:NAD(P)+ oxidoreductase.
