An Escherichia coli clone encoding a single cohesin domain of the cellulosome-integrating protein CipA from Clostridium thermocellum was constructed, and the corresponding polypeptide was purified, treated with papain, and crystallized from a PEG 8000 solution. Crystals exhibit orthorhombic symmetry, space group P2(1)2(1)2(1), with cell dimensions a = 37.7 A, b = 80.7 A, c = 93.3 A, and four or eight molecules in the unit cell. The crystals diffract X-rays to beyond 2 A resolution and are suitable for further crystallographic studies.
