title: Cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of the collagen-binding region of RspB from Erysipelothrix rhusiopathiae.
abstract: RspB is a surface adhesin of Erysipelothrix rhusiopathiae. A recombinant form of the collagen-binding region of this protein, RspB((31-348)), has been overexpressed in Escherichia coli in native and selenomethionine-derivative forms and purified using affinity and gel-permeation chromatography. Thin plate-like crystals were obtained by the hanging-drop vapour-diffusion method using the same condition for both forms. The native crystals diffracted to a resolution of 2.5 A using an in-house X-ray source, while the selenomethionine-derivative crystals diffracted to a resolution of 2.2 A using synchrotron radiation. The crystals belonged to the monoclinic space group P2(1), with unit-cell parameters a = 46.19, b = 66.65, c = 101.72 A, beta = 94.11 degrees .
