Metal-Catalyzed Oxidation of Phenylalanine-Sensitive 3-Deoxy-d-arabino-Heptulosonate-7-Phosphate Synthase from Escherichia coli: Inactivation and Destabilization by Oxidation of Active-Site Cysteines

The in vitro instability of the phenylalanine-sensitive 3-deoxy-d-arabino-heptulosonate-7-phosphate synthase [DAHPS(Phe)] from Escherichia coli has been found to be due to a metal-catalyzed oxidation mechanism. DAHPS(Phe) is one of three differentially feedback-regulated isoforms of the enzyme which...
