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   -!- COFACTOR:
CC       Name=divinyl chlorophyll a; Xref=ChEBI:CHEBI:73095;
CC         Evidence={ECO:0000250|UniProtKB:Q6Q972};
CC   -!- COFACTOR:
CC       Name=divinyl chlorophyll b; Xref=ChEBI:CHEBI:73096;
CC         Evidence={ECO:0000250|UniProtKB:Q6Q972};
CC   -!- SUBUNIT: The antenna complex consists of divinyl chlorophylls (a and b)
CC       and divinyl chlorophyll a/b binding proteins and binds more divinyl
CC       chlorophyll b than does the antenna complex from high-light-adapted
CC       Prochlorococcus. {ECO:0000250|UniProtKB:Q6Q972}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC       {ECO:0000250|UniProtKB:Q6Q972}; Multi-pass membrane protein
CC       {ECO:0000250}.
CC   -!- MISCELLANEOUS: This low-light-adapted strain contains 7 pcb genes.
CC       {ECO:0000303|PubMed:18159947}.
CC   -!- SIMILARITY: Belongs to the PsbB/PsbC family. IsiA/Pcb subfamily.
CC       {ECO:0000305}.
