STRUCTURE OF FERRIC HORSERADISH PEROXIDASE C1A IN COMPLEX WITH ACETATE

Overview

A molecular description of oxygen and peroxide activation in biological, systems is difficult, because electrons liberated during X-ray data, collection reduce the active centres of redox enzymes catalysing these, reactions. Here we describe an effective strategy to obtain crystal, structures for high-valency redox intermediates and present a, three-dimensional movie of the X-ray-driven catalytic reduction of a bound, dioxygen species in horseradish peroxidase (HRP). We also describe, separate experiments in which high-resolution structures could be obtained, for all five oxidation states of HRP, showing such structures with, preserved redox states for the first time.
