RT   c' from two species of purple photosynthetic bacteria.";
RL   Nature 278:661-662(1979).
CC   -!- FUNCTION: Cytochrome c2 is found mainly in purple, non-sulfur,
CC       photosynthetic bacteria where it functions as the electron donor to the
CC       oxidized bacteriochlorophyll in the photophosphorylation pathway.
CC       However, it may also have a role in the respiratory chain and is found
CC       in some non-photosynthetic bacteria.
CC   -!- PTM: Binds 1 heme c group covalently per subunit.
CC   -!- SIMILARITY: Belongs to the cytochrome c family. {ECO:0000305}.
