ENZYME entry: EC 2.6.1.82

Accepted Name
Putrescine aminotransferase.
Alternative Name(s)
PAT.
Putrescine transaminase.
Putrescine-alpha-ketoglutarate transaminase.
Reaction catalysed
Putrescine + 2-oxoglutarate <=> L-glutamate + 1-pyrroline + H(2)O
Cofactor(s)
Pyridoxal 5'-phosphate.
Comment(s)
  • The enzymatic part of the reaction produces 4-aminobutanal that spontaneously cyclizes to form 1-pyrroline, which is a substrate for EC 1.2.1.19.
  • Cadaverine and spermidine can also act as substrates.
  • Forms part of the arginine catabolism pathway.
