Ion-protein coordination: the many faces of a proton.

Victor L Davidson.   

Abstract

A joint X-ray/neutron diffraction study has enabled the direct observation of a hydronium ion coordinated by three amino-acid residues of an enzyme. This sighting will affect our views on how enzymes transport and use protons.
