Lhca1 | PSI type I chlorophyll a/b-binding protein

The light-harvesting protein Lhca1 is one of the four main and highly conserved types of chlorophyll a/b-binding proteins (Lhca1-4) of the light harvesting antenna (LHCI) of plant photosystem I. Lhca1 is imported as a precursor from the cytosol into the chloroplast. Upon insertion into the thylakoid membrane Lhca1 forms a heterodimer (LHCI-730) with Lhca4 that associates with the PSI core close to PsaG and PsaF.A biochemical characterization of the plant LHCI antenna can be found in Klimmek et al. (2005) The structure of the higher plant light harvesting complex I: in vivo characterization and structural interdependence of the Lhca proteins. Biochemistry 44: 3065–3073
