the membrane-bound and soluble co- and no-binding cytochromes c were not spectrally variant cytochromes c , and the redox properties of the soluble cytochrome ( reducible by nadh but not by succinate or ascorbate plus n , n , n ' , n'-tetramethyl-p-phenylenediamine ) suggested that it , at least , was a low-potential cytochrome ;
