ENZYME entry: EC 1.2.1.19

Accepted Name
aminobutyraldehyde dehydrogenase
Alternative Name(s)
1-pyrroline dehydrogenase
4-aminobutanal dehydrogenase
ABALDH
gamma-guanidinobutyraldehyde dehydrogenase
Reaction catalysed
4-aminobutanal + H2O + NAD(+) <=> 4-aminobutanoate + 2 H(+) + NADH
Comment(s)
  • The enzyme from some species exhibits broad substrate specificity and has a marked preference for straight-chain aldehydes (up to 7 carbon atoms) as substrates.
  • The plant enzyme also acts on 4-guanidinobutanal (cf. EC 1.2.1.54).
  • As 1-pyrroline and 4-aminobutanal are in equilibrium and can be interconverted spontaneously, 1-pyrroline may act as the starting substrate.
  • Formerly EC 1.5.1.35.
