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. |
