【 摘 要 】

The cytochrome-containing membrane complexes of the phototrophically grown green non-sulfur bacterium Chloroflexus aurantiacus were fractionated by anion exchange chromatography. Three cytochrome b and four cytochrome c peaks were observed. None of the separated complexes met the features of the cytochrome bc complex. Two main cytochrome b-containing complexes were further purified: a dimer of identical subunits with unknown function and a succinate:quinone oxidoreductase containing three subunit species. Two novel multisubunit complexes, similar to each other, with two heme c-bearing subunits were also purified.
