“…The data in Table I reveal that complex formation with CcP results in very similar complex-induced resonance shifts for horse and tuna ferricytochromes c. For horse and tuna ferricytochromes c, the largest complex-induced resonance shifts occur at the heme 8-CH3 and 3-CH3 resonances and at the heme 7a protons (Table I) (Satterlee et al, 1987a). For the remaining proton resonances listed in Table I and for several other resonances omitted from the table for brevity, the magnitude of complex-induced shifts for horse and tuna ferricytochromes c are either very small or zero.…”

“…Resonance line broadening is also indicative of proteinprotein association (Gupta & Yonetani, 1973;Eley & Moore, 1983;Satterlee et al, 1987a;. Here, it is most readily illustrated by comparing Figure 3 panels A and E, which are typical of results observed for all of the noncovalent complexes formed at low salt.…”

“…It has been speculated that the interaction with a redox partner could trigger a rearrangement of the relative positions of heme and methionine-80 axial ligand and thus of the distribution of electron spin density, thereby facilitating electron transfer (36). Indeed, NMR studies on cytochrome c complexed to various electron donors and acceptors do show such a redistribution of spin density (37). The MCD change might arise, in part, from this phenomenon.…”
