Abstract:
Large single crystals (up to 1 mm in each dimension) of the B800-850 antenna complex from Rhodopseudomonas acidophila strain 10050 have been grown in the presence of beta-octyl-glucoside. These crystals have the space group R32 and unit cell dimensions of a = b = 119.9 A and c = 297.0 A. Recently we have improved our crystallization procedures so that all crystals now diffract reliably to beyond 3.5 A, with some diffracting to below 3 A. A range of isomorphous heavy atom derivatives have been prepared and we are now engaged in locating the heavy atom sites within the unit cell.
