==An icosahedral assembly of light-harvesting chlorophyll a/b protein complex from pea thylakoid membranes==
-
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.
