Name	Putrescine aminotransferase
EC_number	2.6.1.82
CAS_number	98982-73-

Science 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 \rightleftharpoons 1-pyrroline + L-glutamate + H2O (overall reaction) :(1a) putrescine + 2-oxoglutarate \rightleftharpoons 4-aminobutanal + L-glutamate :(1b) 4-aminobutanal \rightleftharpoons 1-pyrroline + H2O (spontaneous)

This enzyme is a pyridoxal-phosphate protein.
