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. In chromophytic algae, LHC is
CC associated with photosystem II, energy being transferred from
CC fucoxanthin and chlorophyll C to chlorophyll A and the photosynthetic
CC reaction centers where it is used to synthesize ATP and 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 the pigments in lhc;
CC fucoxanthin: chlorophyll C: chlorophyll A is (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 -!- SIMILARITY: Belongs to the fucoxanthin chlorophyll protein family.
CC {ECO:0000305}.
