General annotation (Comments)

Function	Catalyzes the oxidation of 1-pyrroline, which is spontaneously formed from 4-aminobutanal, leading to 4-aminobutanoate (GABA) By similarity.
Catalytic activity	4-aminobutanal + NAD+ + H2O = 4-aminobutanoate + NADH. HAMAP MF_01275
Pathway	Amine and polyamine degradation; putrescine degradation; 4-aminobutanoate from 4-aminobutanal: step 1/1. HAMAP MF_01275
Subunit structure	Homotetramer By similarity.
Miscellaneous	4-aminobutanal is also called gamma-aminobutyraldehyde. HAMAP MF_01275
Sequence similarities	Belongs to the aldehyde dehydrogenase family. Gamma-aminobutyraldehyde dehydrogenase subfamily.
