Deciphering the assembly of the Yersinia type III secretion injectisome.
The assembly of the Yersinia enterocolitica type III secretion injectisome was investigated by grafting fluorescent proteins onto several components, YscC (outer-membrane (OM) ring), YscD (forms the inner-membrane (IM) ring together with YscJ), YscN (ATPase), and YscQ (putative C ring). The recombinant injectisomes were functional and appeared as fluorescent spots at the cell periphery. Epistas...
متن کاملPREPARATION AND CHARACTERIZATION OF Mn (III) COMPLEXES
We have prepared and characterized a few Mn (III) complexes by using a few bidentate and tridentate ligands. Spectra of the manganese (III) ion in a variety of molecular environments are reported. On the basis of solution spectra, some of these complexes seem to be typically distorted
متن کاملKinetic Studies of RNA Cleavage by Lanthanide(III) Macrocyclic Complexes
There has been much effort directed in recent years towards the design of catalysts for the cleavage of RNA, and the development of an understanding of the mechanism for the cleavage reaction. There has been significant progress in both areas. However, the rate accelerations reported to date for synthetic catalysts of RNA cleavage are, in general, far below those obtained for enzyme catalysts; ...
متن کاملAtomic resolution structure of the cytoplasmic domain of Yersinia pestis YscU, a regulatory switch involved in type III secretion.
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 A). These crystallographic studies provide structural insights into the conformational change...
متن کاملThe Salmonella type III secretion system virulence effector forms a new hexameric chaperone assembly for export of effector/chaperone complexes.
Bacteria hijack eukaryotic cells by injecting virulence effectors into host cytosol with a type III secretion system (T3SS). Effectors are targeted with their cognate chaperones to hexameric T3SS ATPase at the bacterial membrane's cytosolic face. In this issue of the Journal of Bacteriology, Roblin et al. (P. Roblin, F. Dewitte, V. Villeret, E. G. Biondi, and C. Bompard, J Bacteriol 197:688-698...
