PubMed Abstract: A combination of mass spectrometry, Raman microspectroscopy, circular dichroism and X-ray crystallography has been used to obtain detailed information on the reaction of an iridium-based CO-releasing molecule (Ir-CORM), Cs2IrCl5CO, with a model protein, bovine pancreatic ribonuclease. The results show that Ir-compound fragments bind to the N-terminal amine and close to histidine and methionine side chains, and the CO ligand is retained for a long time. The data provide helpful information for identifying protein targets for Ir-CORMs and for studying the mechanism that allows them to exhibit their interesting biological properties.
