Abstract:
A trypsin-activated CrylA(a) protein from Bacillus thuringiensis has been purified and crystallized. Crystals belong to orthorhombic space group P2(1)2(1)2(1), with cell dimensions a = 53.3, b = 111.3 and c = 154.7 A. The crystals diffract to at least 2.2 angstrum resolution and are suitable for X-ray structural analysis. They contain a single molecule in the asymmetric unit.
