title: Crystallization and preliminary X-ray analysis of porin from Rhodobacter capsulatus.
abstract: Porin monomers of the phototrophic bacterium Rhodobacter capsulatus were purified. Crystals were obtained from a solution of porin solubilized with the detergent octyltetraoxyethylene within 5 days using the vapor phase equilibration technique. The crystals were rhombohedral with an edge length of 0.4 mm. The space group was trigonal R3 with unit cell constants of a = b = 95 A, c = 147 A. Reflexions were observed to 3.2 A.
