== Function ==
-
 
+
[https://www.uniprot.org/uniprot/CB22_PEA CB22_PEA] The light-harvesting complex (LHC) functions as a light receptor, it captures and delivers excitation energy to photosystems with which it is closely associated.<ref>PMID:2174365</ref> May channel protons produced in the catalytic Mn center of water oxidation into the thylakoid lumen.<ref>PMID:2174365</ref>

-
When the light-harvesting chlorophyll a/b protein complex (LHC-II) from pea thylakoid membranes is co-crystallized with native lipids, an octahedral crystal that exhibits no birefringence is obtained. Cryogenic electron micrographs of a crystal edge showed the crystal to be made up of hollow spherical assemblies with a diameter of 250 A. X-ray diffraction data at 9.5 A resolution revealed the spherical shell of LHC-II to have icosahedral symmetry. A T = 1 icosahedral model of LHC-II, in which the stromal surface of the protein faces outward, was constructed using the previously reported structure of the LHC-II trimer [Kuhlbrandt et al. (1994), Nature (London), 367, 614-621]. The present result shows the first example of a well ordered three-dimensional crystal of icosahedral proteoliposomes.
