Preliminary X-ray diffraction analysis of CfaA, a molecular chaperone essential for the assembly of CFA/I fimbriae of human enterotoxigenic Escherichia coli

The molecular chaperone CfaA plays a critical role in the bioassembly of the surface-adhesive CFA/I fimbriae of enterotoxigenic E. coli. Purified CfaA was crystallized and the phase solution was determined by the multiple isomorphous replacement coupled with anomalous scattering method.
