spuc
Description Putrescine--pyruvate aminotransferase (2.6.1.-)
Alternative names Putrescine--pyruvate transaminase;
PATase.
Catalyzed reaction putrescine + pyruvate = 4-aminobutanal + L-alanine.
Cofactor Pyridoxal phosphate.
Comments Distinct from 2.6.1.82 because the preferred ketoacid substrate is pyruvate rather than 2-oxoglutarate.

As with 2.6.1.82, the 4-aminobutanal product is expected to spontaneously cyclize, forming 1-pyrroline.
This activity, however, has never been characterized on a purified protein.
