Abstract

During the epoxidation of allylbenzene, chloroperoxidase (CPO) is converted to an inactive green species in which the prosthetic heme has been modified by addition of the alkene plus an oxygen atom (Dexter, AF; Hager, LP J. Am. Chem. Soc. 1995, 117, 817-818). We have used Q-band continuous wave and pulsed electron-nuclear double resonance (ENDOR) spectroscopy to study the CPO heme in situ following inactivation with ...
