Fig. 4

Room-temperature absorption spectra of soluble cytochromes in the membranes of 8004, 0531pk, C0531 and 015F07. The c-type cytochromes showed peaks at about 552 nm and the b-type cytochromes at about 560 nm. Samples were reduced with sodium dithionite or oxidized with ammonium persulfate. The spectra were reduced-minus-oxidized spectra at equal protein concentrations. Absorption maxima were indicated by arrows
