Abstract

Flavocytochrome c-552, isolated from the photosynthetic purple sulfur bacterium Chromatium vinosum, after linkage to an Affigel 10-affinity matrix, will bind equine and yeast mitochondrial cytochromes c, C. vinosum cytochrome c-550 and cytochrome c 2 from the photosynthetic purple non-sulfur bacterium Rhodo-pseudomonas viridis. Similarly, an equine cytochrome c-Sepharose 4B affinity column will bind the C. vinosum flavocytochrome c-552 and its separated heme-containing subunit. These results and the correlation between the effect of ionic strength on binding of the flavocytochrome c-552 to cytochrome c and on the sulfide:cytochrome c oxidoreductase activity catalyzed by C. vinosum flavocytochrome c-552 support the idea of the involvement of an electrostatic complex between the two proteins during sulfide oxidation.
