RT "The tomato Cab-4 and Cab-5 genes encode a second type of CAB polypeptides
RT localized in photosystem II.";
RL Plant Mol. Biol. 9:109-120(1987).
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.
CC -!- COFACTOR:
CC Note=Binds at least 14 chlorophylls (8 Chl-a and 6 Chl-b) and
CC carotenoids such as lutein and neoxanthin. {ECO:0000250};
CC -!- SUBUNIT: The LHC complex consists of chlorophyll a-b binding proteins.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; Multi-
CC pass membrane protein.
CC -!- DOMAIN: The N-terminus of the protein extends into the stroma where it
CC is involved with adhesion of granal membranes and post-translational
CC modifications; both are believed to mediate the distribution of
CC excitation energy between photosystems I and II.
CC -!- PTM: Photoregulated by reversible phosphorylation of its threonine
CC residues. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the light-harvesting chlorophyll a/b-binding
CC (LHC) protein family. {ECO:0000305}.
