UniProt Comments
Function: The light-harvesting complex (LHC) functions as a light receptor, it captures and delivers excitation energy to photosystems with which it is closely associated.Cofactor: Binds at least 14 chlorophylls (8 Chl-a and 6 Chl-b) and carotenoids such as lutein and neoxanthin By similarity.Subunit structure: The LHC complex consists of chlorophyll a-b binding proteins.Subcellular location: Plastid › chloroplast thylakoid membrane; Multi-pass membrane protein. Domain: The N-terminus of the protein extends into the stroma where it is involved with adhesion of granal membranes and post-translational modifications; both are believed to mediate the distribution of excitation energy between photosystems I and II.Post-translational modification: Photoregulated by reversible phosphorylation of its threonine residues By similarity.Sequence similarities: Belongs to the light-harvesting chlorophyll a/b-binding (LHC) protein family.
