'''X-RAY INDUCED REDUCTION OF HORSERADISH PEROXIDASE C1A COMPOUND III (0-11% DOSE)'''<br />


==Overview==
==X-ray induced reduction of horseradish peroxidase C1A Compound III (0-11% dose)==
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.

Publication Abstract from PubMed

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.
