CC   -!- FUNCTION: Antenna complexes are light-harvesting systems, which
CC       transfer the excitation energy to the reaction centers.
CC   -!- SUBUNIT: The core complex is formed by different alpha and beta chains,
CC       binding bacteriochlorophyll molecules, and arranged most probably in
CC       tetrameric structures disposed around the reaction center. The non-
CC       pigmented gamma chains may constitute additional components.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane; Single-pass type II membrane
CC       protein.
CC   -!- SIMILARITY: Belongs to the antenna complex beta subunit family.
CC       {ECO:0000305}.
