Multifrequency high-field EPR study of the tryptophanyl and tyrosyl radical intermediates in wild-type and the W191G mutant of cytochrome c peroxidase.

Journal of the American Chemical Society - 30 May 2001

Ivancich A, Dorlet P, Goodin D B, Un S

Abstract excerpt

Multifrequency (95, 190, and 285 GHz) high-field electron paramagnetic resonance (EPR) spectroscopy has been used to characterize radical intermediates in wild-type and Trp191Gly mutant cytochrome c peroxidase (CcP). The high-field EPR spectra of the exchange-coupled oxoferryl--trytophanyl radical pair that constitutes the CcP compound I intermediate [(Fe(IV)=O) Trp*(+)] were analyzed using a spin Hamiltonian...
