This entry represents putrescine aminotransferase (EC: as found in Escherichia coli [PMID: 3510672], Erwinia carotovora subsp. atroseptica (Pectobacterium atrosepticum), and closely related species. Putrescine aminotransferase catalyzes the aminotransferase reaction from putrescine to 2-oxoglutarate, leading to glutamate and 4-aminobutanal, which spontaneously cyclizes to form 1-pyrroline. This pyridoxal phosphate enzyme, as characterised in E. coli, can also act on cadaverine and, more weakly, spermidine.
