CC -!- FUNCTION: The reaction center is a membrane-bound complex that mediates
CC the initial photochemical event in the electron transfer process of
CC photosynthesis.
CC -!- SUBUNIT: Reaction center is composed of four bacteriochlorophylls, two
CC bacteriopheophytins, two ubiquinones, one iron, and two highly
CC hydrophobic polypeptide chains (designated L and M).
CC -!- SUBCELLULAR LOCATION: Cellular chromatophore membrane {ECO:0000250};
CC Multi-pass membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the reaction center PufL/M/PsbA/D family.
CC {ECO:0000305}.
