Abstract Chlorobium phaeobacteroides contains two soluble basic c-type cytochromes, a flavocytochrome c-552 and a small cytochrome c-555. Both electron transfer proteins were highly purified by ion exchange chromatography and gel filtration. The flavocytochrome c-552 exhibits maxima at 552 nm, 523 nm and 416 nm in the reduced state and at 409.5 nm with two shoulders at 440 nm and 480 nm in the oxidized form. The best purity index (A280/A416)obtained was 0.65. The molecular properties of this flavocytochrome are as follows: isoelectric point, pH 9.5 - 10; redox potential, +63 mV; molecular weight, 56,000. Cytochrome c-555 is a small basic hemoprotein with an isoelectric point of pH 9.5 - 10, a molecular weight of 9,500 and a midpoint redox potential of +105 mV. The best purity index {A280/A418) obtained was 0.176. The oxidized form of this cytochrome has a maximum at 411.5 nm, while the reduced state shows three maxima (α-band at 554.5 nm; β-band at 523 nm, and γ-band at 418 nm). The a-band is asymmetrical with a typical shoulder at 551 nm.
