Abstract

X-ray absorption fine structure (XAFS) measurements were made of native cytochrome c, denatured cytochrome c and its CO-bonded form. Our results show that the local structure around the heme site in denatured ferrous cytochrome c is not significantly different from the one in native ferrous cytochrome c. Our results also indicate that when CO binds to denatured ferrous cytochrome c, CO takes place of the S ligand, possible unfolding the denatured ferrous cytochrome c further.
