EPR studies on compound I of horseradish peroxidase.

R Aasa, T Vanngård.   

Abstract

Compound I of horseradish peroxidase (donor: hydrogen-peroxide oxidoreductase EC 1.11.1.7) was studied by EPR at low temperatures. An asymmetric signal was found, about 15 Gauss wide and with a g-value of 1.995, which could be detected only at temperatures below 20 K and which had an intensity corresponding to about 1% of the heme content. In a titration with H2O2, the signal intensity was proportional to the concentration of Compound I, reaching a maximum when equivalent amounts of H2O2 were added. This indicates that the signal is not due to an impurity, and it is suggested that a free radical is formed, relaxed by a near-by fast-relaxing iron.
