Cytochrome c′ folding triggered by electron transfer: Fast and slow formation of four-helix bundles

Reduced (Fe(II)) Rhodopseudomonas palustris cytochrome c′ (Cyt c′) is more stable toward unfolding ([GuHCl](1/2) = 2.9(1) M) than the oxidized (Fe(III)) protein ([GuHCl](1/2) = 1.9(1) M). The difference in folding free energies (ΔΔG(f)° = 70 meV) is less than half of the difference in reduction pote...
