Preliminary X-ray studies on two new crystal forms of staphylococcal enterotoxin C2.
Two new crystal forms of staphylococcal enterotoxin C2 have been obtained by vapor-diffusion methods. Form 1 crystals are monoclinic in space group P2(1) with cell dimensions a = 43.43, b = 69.92, c = 42.22 A, 8 = 90.1 degrees and diffract to at least 2.7 A resolution. Form 2 crystals are tetragonal in space group P4(1)2(1)2 or P4(3)2(1)2 with cell dimensions a = b = 42.98, c = 289.92 A and diffract to 1.9 A resolution.
