Putrescine aminotransferase (EC 2.6.1.82, putrescine-alpha-ketoglutarate transaminase, YgjG, putrescine:alpha-ketoglutarate aminotransferase, PAT, putrescine:2-oxoglutarate aminotransferase, putrescine transaminase) is an enzyme with systematic name butane-1,4-diamine:2-oxoglutarate aminotransferase.[1][2][3] This enzyme catalyses the following chemical reaction
- putrescine + 2-oxoglutarate 1-pyrroline + L-glutamate + H2O (overall reaction)
- (1a) putrescine + 2-oxoglutarate 4-aminobutanal + L-glutamate
- (1b) 4-aminobutanal 1-pyrroline + H2O (spontaneous)
This enzyme is a pyridoxal-phosphate protein.
