Title: Expression, purification and preliminary X-ray analysis of the Neisseria meningitidis outer membrane protein PorB

Journal Article · · Acta Crystallogr. F

The Neisseria meningitidis outer membrane protein PorB was expressed in Escherichia coli and purified from inclusion bodies by denaturation in urea followed by refolding in buffered LDAO on a size-exclusion column. PorB has been crystallized in three different crystal forms: C222, R32 and P6{sub 3}. The C222 crystal form may contain either one or two PorB monomers in the asymmetric unit, while both the R32 and P6{sub 3} crystal forms contained one PorB monomer in the asymmetric unit. Of the three, the P6{sub 3} crystal form had the best diffraction quality, yielding data extending to 2.3 {angstrom} resolution.
