Body temperature protein X-ray crystallography at 37 °C: a rhenium protein complex seeking a physiological condition structure

Abstract

The retention of the covalent binding of an organometalllic rhenium complex as a model for a technetium-99m imaging agent, to a protein at physiological body temperature 37 °C is described. Detailed structure comparisons are made to the related 100 K crystal structure. The generality of the need for this sort of analytical procedure for guiding ligand lead compound discovery is emphasised.
