STRUCTURE OF HORSERADISH PEROXIDASE C1A COMPOUND III


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.

About this Structure

1H57 is a Single protein structure of sequence from Armoracia rusticana. Full crystallographic information is available from OCA.
