产品介绍： The light-harvesting protein Lhca3 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. Lhca3 is imported as a precursor from the cytosol into the chloroplast. Upon integration in the thylakoid membrane Lhca3 forms a heterodimer (LHCI-680) with Lhca2 that associates with the PSI core close to PsaF and PsaK. 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.
