Function and Biology Details

Reactions catalysed:
4-aminobutanal + NAD(+) + H(2)O = 4-aminobutanoate + NADH
4-trimethylammoniobutanal + NAD(+) + H(2)O = 4-trimethylammoniobutanoate + NADH
4-guanidinobutanal + NAD(+) + H(2)O = 4-guanidinobutanoate + NADH
Betaine aldehyde + NAD(+) + H(2)O = betaine + NADH
