General annotation (Comments)

Function

Catalyzes the oxidation of 1-pyrroline, which is spontaneously formed from 4-aminobutanal, leading to 4-aminobutanoate (GABA) By similarity. HAMAP MF_01275

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. HAMAP MF_01275

Miscellaneous

4-aminobutanal is also called gamma-aminobutyraldehyde. HAMAP MF_01275

Sequence similarities

Belongs to the aldehyde dehydrogenase family. Gamma-aminobutyraldehyde dehydrogenase subfamily.
