Abstract

Survival E (SurE) protein from Campylobacter jejuni, a Gram-negative mesophile, has been overexpressed in Escherichia coli as a soluble protein, successfully purified and crystallized in two distinct crystal forms. The first form belongs to space group P2(1)2(1)2(1), with a tetramer in the asymmetric unit and unit-cell parameters a = 80.5, b = 119.0, c = 135.3 A. The second form belongs to space group C2, with unit-cell parameters a = 121.4, b = 47.1, c = 97.8 A, and contains a dimer in the asymmetric unit. Diffraction data have been collected from these crystal forms to 2.5 and 2.95 A resolution, respectively.
