X-RAY DIFFRACTION	5.20	?	THE CRYSTALLIZATION CONSISTS OF TWO STEPS. FIRST, A MIXTURE OF 5 MG/ML PURPLE MEMBRANE, 0.25% OTG, 1 M AMMONIUM SULFATE, 0.16 M NACL, 0.04 M SODIUM CITRATE (PH5.2) , 0.04% NAN3 WAS INCUBATED AND 15% TREHALOSE AT 305K FOR 5 DAYS. THIS RESULTED IN THE FORMATION OF SPHERICAL VESICLES WITH A DIAMETER OF 50 NM. AFTER SEDIMENTAL MATERIALS WERE REMOVED BY CENTRIFUGATION (4000G X 10 MIN), A SUSPENSION OF THE SPHERICAL VESICLES WAS COOLED TO 278K AND CONCENTRATED BY VAPOR DIFFUSION AGAINST A RESERVOIR SOLUTION CONTAINING 2.0 M AMMONIUM SULFATE 0.08M SODIUM CITRATE (PH 5.2) AND 30% TREHALOSE. INCUBATION FOR A COUPLE OF MONTHS YIELDED HEXAGONAL CRYSTALS.
