Protein

Putrescine aminotransferase

Gene

patA

Organism
Enterobacter sp. (strain 638)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the aminotransferase reaction from putrescine to 2-oxoglutarate, leading to glutamate and 4-aminobutanal, which spontaneously cyclizes to form 1-pyrroline. Is also able to transaminate cadaverine and, in lower extent, spermidine, but not ornithine.UniRule annotation

Catalytic activityi

Putrescine + 2-oxoglutarate = L-glutamate + 1-pyrroline + H2O.UniRule annotation

Cofactori

pyridoxal 5'-phosphateUniRule annotation

Pathwayi: putrescine degradation

This protein is involved in step 1 of the subpathway that synthesizes 4-aminobutanal from putrescine (transaminase route).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Putrescine aminotransferase (patA)
This subpathway is part of the pathway putrescine degradation, which is itself part of Amine and polyamine degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 4-aminobutanal from putrescine (transaminase route), the pathway putrescine degradation and in Amine and polyamine degradation.
