CC -!- FUNCTION: Catalyzes the aminotransferase reaction from putrescine to 2-
CC oxoglutarate, leading to glutamate and 4-aminobutanal, which
CC spontaneously cyclizes to form 1-pyrroline. This is the first step in
CC one of two pathways for putrescine degradation, where putrescine is
CC converted into 4-aminobutanoate (gamma-aminobutyrate or GABA) via 4-
CC aminobutanal. Also functions as a cadaverine transaminase in a a L-
CC lysine degradation pathway to succinate that proceeds via cadaverine,
CC glutarate and L-2-hydroxyglutarate. {ECO:0000255|HAMAP-Rule:MF_01276}.
