title: N-(5'-Phosphopyridoxyl)-4-aminobutyric acid: a stabel bisubstrate adduct inhibitor of rat brain 4-aminobutyric acid aminotransferase.
abstract: N-(5'-Phosphophopyridoxyl)-4-aminobutyric acid, a stable adduct of pyridoxal phosphate and 4-aminobutyrate acid, has been shown to be a potent inhibitor of rat brain 4-aminobutyric acid aminotransferase (GABA-T) with a K1 of 1.4 muM.
