CC -!- FUNCTION: Catalyzes the oxidation 4-aminobutanal (gamma-
CC aminobutyraldehyde) to 4-aminobutanoate (gamma-aminobutyrate or GABA).
CC This is the second step in one of two pathways for putrescine
CC degradation, where putrescine is converted into 4-aminobutanoate via 4-
CC aminobutanal. Also functions as a 5-aminopentanal dehydrogenase in a a
CC L-lysine degradation pathway to succinate that proceeds via cadaverine,
CC glutarate and L-2-hydroxyglutarate. {ECO:0000255|HAMAP-Rule:MF_01275}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=4-aminobutanal + H2O + NAD(+) = 4-aminobutanoate + 2 H(+) +
CC NADH; Xref=Rhea:RHEA:19105, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:19106;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01275};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-aminopentanal + H2O + NAD(+) = 5-aminopentanoate + 2 H(+) +
CC NADH; Xref=Rhea:RHEA:61632, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:144896,
CC ChEBI:CHEBI:356010; Evidence={ECO:0000255|HAMAP-Rule:MF_01275};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:61633;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01275};
CC -!- PATHWAY: Amine and polyamine degradation; putrescine degradation; 4-
CC aminobutanoate from 4-aminobutanal: step 1/1. {ECO:0000255|HAMAP-
CC Rule:MF_01275}.
CC -!- PATHWAY: Amino-acid degradation. {ECO:0000255|HAMAP-Rule:MF_01275}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_01275}.
CC -!- MISCELLANEOUS: 4-aminobutanal can spontaneously cyclize to 1-pyrroline,
CC and 5-aminopentanal to 1-piperideine. {ECO:0000255|HAMAP-
CC Rule:MF_01275}.
CC -!- SIMILARITY: Belongs to the aldehyde dehydrogenase family. Gamma-
CC aminobutyraldehyde dehydrogenase subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_01275}.
