the relative reactivities toward reduction by free flavin semiquinones of cytochromes ( c-type cytochromes , cytochrome b5 , c'-type cytochromes ) iron-sulfur proteins ( high-redox-potential ferredoxins , rubredoxins , low-redox-potential ferredoxins ) , and blue copper proteins ( plastocyanin , azurins ) are shown to correlate with calculations of the solvent exposure of the various prosthetic groups .
