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 Å, c=147 Å. Reflexions were observed to 3.2 Å. © 1989.
