Crystallization and preliminary X-ray analysis of phosphoporin from the outer membrane of Escherichia coli.
Phosphoporin is a pore-forming transmembrane protein that spans the outer membrane of Escherichia coli and facilitates the diffusion of phosphates and phosphorylated compounds. Phosphoporin has been crystallized in several different crystal forms, although only one appears to be suitable for X-ray analysis. These crystals, which are hexagonal plates, diffract X-rays to 3 A resolution and belong to the space-group P6(3)22, with unit cell dimensions a = b = 121 A and c = 111 A.
