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 alpha subunit family.
CC {ECO:0000305}.
