"Crystal structures of cleaved and uncleaved forms of the YscU cytoplasmic domain, an essential component of the type III secretion system (T3SS) in Yersinia pestis, have been solved by single-wavelength anomolous dispersion and refined with X-ray diffraction data extending up to atomic resolution (1.13 angstrom). These crystallographic studies provide structural insights into the conformational changes induced upon auto-cleavage of the cytoplasmic domain of YscU," scientists writing in the journal Protein Science report. "The structures indicate that the cleaved fragments remain bound to each other. The conserved NPTH sequence that contains the site of the...
