Mössbauer spectra of the heme peptide (HP) 1-50 and the heme peptide:non-heme peptide (NHP) non-covalent complex 1-50:51-104 derived from cytochrome c: evidence for cytochrome c iron site solvation in aqueous solution.
Mössbauer spectroscopic studies on a heme peptide (HP) derived from cytochrome c and on the HP recombined non-covalently with the remaining cleaved section are reported. The results suggest that the environment of the heme site in the known crystal structure of cytochrome c may differ in detail from the environment of the heme in the working protein.
