CATALYSIS OF PLASTOCYANIN ELECTRON SELF-EXCHANGE BY REDOX-INERT MULTIVALENT CATIONS

Abstract:

Electron self-exchange in solutions of the 'blue' copper protein plastocyanin is catalysed by the redox-inert multivalent cations Mg2+ or Co(NH3)3+6. Measurements of specific 1H-NMR line broadening with 50% reduced solutions in the presence of these cations show that electron exchange proceeds through encounters of cation-protein complexes which dissociate at high ionic strength. In the presence of 8mM (5 equivalents/total protein) Co(NH3)3+6, with 10 mM cacodylate (pH*6.0) as background elec...
