Crystallization and preliminary X-ray analysis of Borrelia burgdorferi outer surface protein C (OspC).

Single crystals of the outer surface protein C (OspC) from Borrelia burgdorferi HB19 have been obtained by the vapor-diffusion method. These crystals belong to space group P2(1), with unit-cell parameters a = 66.218, b = 46.113, c = 112.079 A, beta = 99.30 degrees, and diffract to at least 2.2 A resolution. Native data have been collected from flash-frozen crystals at the National Synchrotron facility of Brookhaven National Laboratory. There are two dimers per asymmetric unit, related by a non-crystallographic twofold axis and a pseudo-translational symmetry.
