Research Abstract

Heme oxygenase (HO) catalyses the degradation of heme via three successive monooxygenase reactions. To probe the cleavage mechanism of oxaporphyrin ring of ferrous a-verdoheme, an intermediate in the HO reaction, ferrous verdoheme-rat HO-1 complex was prepared under anaerobic conditions. Electrochemical reduction of the complex was performed under anaerobic conditions and the reduction potential for one-electron reduction of the oxaporphyrin ring of ferrous verdoheme was determined. Effects of ligands such as CO on the electrochemical reduction and the electron transfer from NADPH-cytochrome P450 reductase to the complex were investigated. In addition, the crystal structure of rat HO-1 in complex with ferrous a -verdoheme was determined. On the basis of results in these experiments, the degradation mechanism of ferrous verdoheme under the physiological condition has discussed.
