title: Inactivation of gamma-aminobutyric acid aminotransferase by (S)-4-amino-4,5-dihydro-2-furancarboxylic acid does not proceed by the expected aromatization mechanism.
abstract: Inactivation of pyridoxal 5'-phosphate (PLP)-dependent gamma-aminobutryic acid aminotransferase by (S)-4-amino-4,5-dihydro-2-furancarboxylic acid (SADFA) gives pyridoxamine 5'-phosphate, not the expected SADFA-PLP aromatization product. Inactivation appears to proceed by a Michael addition/hydrolysis mechanism instead.
