Electron Transfer to Ferricytochrome c: Reaction with Hydrated Electrons and Conformational Transitions Involved
AUTOR(ES)
Pecht, Israel
RESUMO
The reaction of horse-heart cytochrome c with hydrated electrons has been studied by the pulseradiolysis technique. In neutral solution, the ferriheme group was reduced in a bimolecular reaction that takes place at a rate equal to that of the decay of the e-aq, and approaches the diffusion-controlled limit. This reduction is assigned mainly to a direct reaction, proceeding via the exposed edge of the porphyrin projecting into the cytochrome c crevice.
