CC   -!- FUNCTION: The antenna complex functions as a light receptor, it
CC       captures and delivers excitation energy to photosystems II and I. The
CC       Prochlorales pcb genes are not related to higher plant LHCs.
CC       {ECO:0000250|UniProtKB:Q6Q972}.

CC       Note=Chlorophyll b. {ECO:0000250|UniProtKB:Q6Q972};
CC   -!- SUBUNIT: The antenna complex consists of chlorophylls (a and b) and
CC       chlorophyll a/b binding proteins. {ECO:0000250|UniProtKB:Q6Q972}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC       {ECO:0000250|UniProtKB:Q6Q972}; Multi-pass membrane protein
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the PsbB/PsbC family. IsiA/Pcb subfamily.
