NADP-dependent alcohol dehydrogenase with a broad substrate specificity. The oxidative reactions are more than 100 times less efficient than the corresponding reductions, suggesting that the enzyme acts as an aldehyde reductase, rather than as an alcohol dehydrogenase. a primary alcohol + NADP(+) = an aldehyde + H(+) + NADPH Binds 2 Zn(2+) ions per subunit. Homodimer. Present with 2870 molecules/cell in log phase SD medium. Belongs to the zinc-containing alcohol dehydrogenase family.
