title: Expression, purification and crystallization of a collagen-binding fragment of Yersinia adhesin YadA.
abstract: A recombinant form of a collagen-binding fragment of Yersinia enterocolitica serotype O:3 adhesin YadA with an N-terminal polyhistidine affinity tag has been produced in Escherichia coli, purified and crystallized using the sitting-drop vapour-diffusion technique. Crystals belong to the trigonal space group R3, with unit-cell parameters a = b = 67.05, c = 221.95 A, and diffract to 1.55 A resolution on a synchrotron-radiation source.
