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, ECO:0000303|PubMed:10725393,
CC ECO:0000303|Ref.3}.
CC -!- COFACTOR:
CC Name=divinyl chlorophyll a; Xref=ChEBI:CHEBI:73095;
CC Evidence={ECO:0000303|Ref.3};
CC -!- COFACTOR:
CC Name=divinyl chlorophyll b; Xref=ChEBI:CHEBI:73096;
CC Evidence={ECO:0000303|Ref.3};
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.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000269|Ref.3};
CC Multi-pass membrane protein {ECO:0000250}.
CC -!- INDUCTION: This transcript is too unstable to be able to determine its
CC expression levels. The whole antenna complex is most highly expressed
CC under low light; as the light levels increase antenna complex levels
CC decrease. Thus at least in this strain the amount of antenna complex is
CC controlled mostly at a post-transcriptional level. Transcription
CC decreases upon iron starvation. {ECO:0000269|PubMed:11575723,
CC ECO:0000269|PubMed:12944966}.
CC -!- MISCELLANEOUS: This low-light-adapted strain contains 8 pcb genes.
CC {ECO:0000303|PubMed:12917486, ECO:0000303|PubMed:12944966}.
CC -!- SIMILARITY: Belongs to the PsbB/PsbC family. IsiA/Pcb subfamily.
CC {ECO:0000305}.
