Crystallization and preliminary X-ray characterization of maltoporin from Escherichia coli.
Crystals of maltoporin (the bacteriophage lambda receptor of Escherichia coli) that diffract X-rays to 3 A resolution can be grown reproducibly. Maltoporin is an integral membrane protein, which forms a channel in the E. coli outer membrane that specifically facilitates the diffusion of maltose and maltodextrins. The crystals have a rhombic prismatic habit and belong to the orthorhombic space group C222(1) with unit cell dimensions a = 130 A, b = 213 A and c = 216 A. X-ray structure determination is underway.
