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}.
