CC   -!- FUNCTION: The light-harvesting complex (LHC) functions as a light
CC       receptor, it captures and delivers excitation energy to photosystems
CC       with which it is closely associated. Energy is transferred from the
CC       carotenoid and chlorophyll C (or B) to chlorophyll A and the
CC       photosynthetic reaction centers where it is used to synthesize ATP and
CC       reducing power.
CC   -!- SUBUNIT: The LHC complex of chromophytic algae is composed of
CC       fucoxanthin, chlorophyll A and C bound non-covalently by fucoxanthin
CC       chlorophyll proteins (FCPs). The ratio of pigments in this LHC is;
CC       fucoxanthin: chlorophyll C: chlorophyll A; (0.6-1): (0.1-0.3): (1).
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; Multi-
CC       pass membrane protein. Note=FCPs are probably transported across the
CC       endoplasmic reticulum membranes that surround the plastid via a signal
CC       peptide, followed by translocation across the thylakoid membrane via a
CC       transit peptide.
CC   -!- INDUCTION: Levels are increased twofold when transferred from high
CC       intensity to low intensity blue or white light.
CC   -!- SIMILARITY: Belongs to the fucoxanthin chlorophyll protein family.
CC       {ECO:0000305}.
