Mutational analyses of the photosynthetic reaction center-bound triheme cytochrome subunit and cytochrome c(sub)2 in the purple bacterium Rhodovulum sulfidophilum

Research indicates that in Rhodovulum sulfidophilum cytochrome c(sub)2 is not the dominant electron donor to reaction center as a soluble cytochrome, c-549, donates electron to the reaction center-bound triheme cytochrome. This process is different from those of other purple bacteria.
