What is Electron‐transfer self‐exchange of trimethylphosphine‐modified cytochrome c : NMR study and kinetics using spin‐lattice relaxation times about?

## Abstract The binding of trimethylphosphine to the axial position of the haeme iron in modified cytochrome __c__ by alkylation of methionine was studied by NMR spectroscopy. Electron self‐exchange was determined by spin‐lattice relaxation time (__T__~1~) measurement. The rate is 7.5 × 10^3^ 1 mol^−1^ s^−1^ at 25°C in 0.1 M phosphate buffer (pH 7.0). Two‐dimensional transfer spectroscopy was used to locate haeme methyl resonances in both iron(II) and iron(III) complexes of modified cytochrome __c__.
