Any of the granules, approximately 32 nm x 48 nm and consisting of highly aggregated phycobiliproteins, that are attached in arrays to the external face of a thylakoid membrane in algae of the phyla Cyanophyta and Rhodophyta, where they function as light-harvesting devices in photosynthesis. Excitation energy in the phycobilisome flows in the sequence: phycoerythrin, phycocyanin, allophycocyanin before passing to the antenna chlorophyll of photosystem II.

Protein complex that surrounds and transfers excitation energy directly to the bacterial reaction center; binds bacteriochlorophyll a and has a single absorption band between 870 and 890 nm.

Protein-pigment complex that absorbs light at 800 and 820 nm; is peripherally associated to the bacterial reaction center; transfers excitation energy to the B875 antenna complex.

Protein-pigment complex that absorbs light at 800 and 850 nm; is peripherally associated to the bacterial reaction center; transfers excitation energy to the B875 antenna complex.

A pigment protein complex that forms part of the photosystem I associated light-harvesting complex I; contains two proteins (usually about 24 and 21.5 kDa); has a fluorescence maximum between 680 and 690 nm.
