Structure of ALDH7A1 mutant R441C complexed with NAD

Source organism: Homo sapiens
Entry authors: Korasick DA, Tanner JJ

Function and Biology Details

Reactions catalysed:
(1a) (S)-2-amino-6-oxohexanoate = (S)-2,3,4,5-tetrahydropyridine-2-carboxylate + H(2)O (spontaneous)
An aldehyde + NAD(+) + H(2)O = a carboxylate + NADH
Betaine aldehyde + NAD(+) + H(2)O = betaine + NADH
Cellular component:
