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. {ECO:0000256|ARBA:ARBA00002611,
CC ECO:0000256|RuleBase:RU364137}.
CC -!- SUBUNIT: Reaction center is composed of four bacteriochlorophylls, two
CC bacteriopheophytins, two ubiquinones, one iron, and highly hydrophobic
CC polypeptide chains. {ECO:0000256|RuleBase:RU364137}.
CC -!- SUBCELLULAR LOCATION: Cellular chromatophore membrane
CC {ECO:0000256|RuleBase:RU364137}; Multi-pass membrane protein
CC {ECO:0000256|RuleBase:RU364137}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the reaction center PufL/M/PsbA/D family.
CC {ECO:0000256|ARBA:ARBA00008204, ECO:0000256|RuleBase:RU004331}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:RVT50788.1}.
