EC Tree
IUBMB Comments
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 gamma-guanidinobutyraldehyde dehydrogenase). As 1-pyrroline and 4-aminobutanal are in equilibrium and can be interconverted spontaneously, 1-pyrroline may act as the starting substrate. The enzyme forms part of the arginine-catabolism pathway and belongs in the aldehyde dehydrogenase superfamily .
