CC -!- FUNCTION: Antenna complexes are light-harvesting systems, which
CC transfer the excitation energy to the reaction centers.
CC -!- SUBUNIT: An alpha/beta heterodimer. The core complex is formed by
CC different alpha and beta chains, binding bacteriochlorophyll molecules,
CC and arranged most probably in tetrameric structures disposed around the
CC reaction center. The non-pigmented gamma chains may constitute
CC additional components (By similarity). {ECO:0000250}.
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}.
