Putrescine aminotransferase
Putrescine aminotransferase (, 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. 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.
