The reaction of water-soluble cytochrome c (c(2)) with its physiological redox partners is facilitated by electrostatic attractions between the two protein surfaces. Using spin-labeled cytochrome c(2) from Rhodobacter capsulatus and pulse electron paramagnetic resonance (EPR) measurements we compared spatial orientation of cytochrome c(2) upon its binding… CONTINUE READING
