. "Component of an antenna complex or protein regulating the expression of such components. Antenna complexes are light-harvesting systems (LHC) which are protein-pigment complexes in or on photosynthetic membranes. LHCs receive radiant energy and transfer it to the reaction centers; an array of LHCs is often referred to as an \"antenna\". LHCs typically include one or more associated pigments (phycobilins, chlorophylls, bacteriochlorophylls and carotenoids)." . . "Antenna complex" . "Light-harvesting antenna" .
