Characterization of the blue copper site in oxidized azurin by extended x-ray absorption fine structure: Determination of a short Cu-S distance.

T D Tullius1, P Frank, K O Hodgson.   

Abstract

The primary coordination environment of the "blue" copper ion in oxidized azurin has been elucidated by x-ray absorption spectroscopy. The most striking feature is the unambiguous presence of a very short copper-sulfur distance at 2.10 +/- 0.02 A. Nitrogen ligands, presumed to be from imidazoles, are found at 1.97 A. There is some evidence that the copper coordination sphere may be completed by a second sulfur, the distance of which is determined with much less certainty.
