pubpic2012yuWe report a residue-specific characterization of the thermal unfolding mechanism of cyt c using C-D bonds site-specifically incorporated at residues dispersed throughout three different structural elements within the protein. Elucidation of the detailed unfolding mechanism and the structure of the associated molten globule, both of which represent challenges to conventional techniques, are highlights of the utility of the C-D technique.
