Comments [?]

Function Catalyzes the oxidation 4-aminobutanal (gamma-aminobutyraldehyde) to 4-aminobutanoate (gamma-aminobutyrate or GABA). This is the second step in one of two pathways for putrescine degradation, where putrescine is converted into 4-aminobutanoate via 4-aminobutanal. Also functions as a 5-aminopentanal dehydrogenase in a a L-lysine degradation pathway to succinate that proceeds via cadaverine, glutarate and L-2-hydroxyglutarate.
Catalytic activity RHEA:19105: 4-aminobutanal + H2O + NAD(+) = 4-aminobutanoate + 2 H(+) + NADH
EC 1.2.1.19
PhysiologicalDirection=left-to-right (RHEA:19106)
RHEA:61632: 5-aminopentanal + H2O + NAD(+) = 5-aminopentanoate + 2 H(+) + NADH
PhysiologicalDirection=left-to-right (RHEA:61633)
Pathway Amine and polyamine degradation; putrescine degradation; 4-aminobutanoate from 4-aminobutanal: step 1/1.
Amino-acid degradation.
Subunit Homotetramer.
Miscellaneous 4-aminobutanal can spontaneously cyclize to 1-pyrroline, and 5-aminopentanal to 1-piperideine.
Similarity Belongs to the aldehyde dehydrogenase family. Gamma-aminobutyraldehyde dehydrogenase subfamily.
