Structure of human ALDH1A1 with inhibitor CM026


Function and Biology Details

Reactions catalysed:
4-aminobutanal + NAD(+) + H(2)O = 4-aminobutanoate + NADH
An aldehyde + NAD(+) + H(2)O = a carboxylate + NADH
Benzaldehyde + NAD(+) + H(2)O = benzoate + NADH
Retinal + NAD(+) + H(2)O = retinoate + NADH
