Fas (CD95, Apo-1, or TNFRSF6) is a prototypical apoptosis-inducing death receptor in the tumor necrosis factor receptor (TNFR) superfamily. While the extracellular domains of TNFRs form trimeric complexes with their ligands and the intracellular domains engage in higher-order oligomerization, the role of the transmembrane (TM) domains is unknown. We determined the NMR structures of mouse and hu...
Deep rought mutants, which produce very defective lipopolysaccharides, are unable to export normal levels of porins into the outer membrane. In this study, we showed that lipopolysaccharides from such mutants were also unable to facilitate the trimerization, in vitro, of monomeric OmpF porin secreted by spheroplasts of Escherichia coli B/r. In contrast, lipopolysaccharides containing most or al...
DCP1 stimulates the decapping enzyme DCP2, which removes the mRNA 5' cap structure committing mRNAs to degradation. In multicellular eukaryotes, DCP1-DCP2 interaction is stabilized by additional proteins, including EDC4. However, most information on DCP2 activation stems from studies in S. cerevisiae, which lacks EDC4. Furthermore, DCP1 orthologs from multicellular eukaryotes have a C-terminal ...
Copper resistance is a key virulence trait of the uropathogen Proteus mirabilis. Here we show that P. mirabilis ScsC (PmScsC) contributes to this defence mechanism by enabling swarming in the presence of copper. We also demonstrate that PmScsC is a thioredoxin-like disulfide isomerase but, unlike other characterized proteins in this family, it is trimeric. PmScsC trimerization and its active si...
The matrix (MA) domain of HIV Gag has important functions in directing the trafficking of Gag to sites of assembly and mediating the incorporation of the envelope glycoprotein (Env) into assembling particles. HIV-1 MA has been shown to form trimers in vitro; however, neither the presence nor the role of MA trimers has been documented in HIV-1 virions. We developed a cross-linking strategy to re...
Native rabies virus glycoprotein (RVGvir) is a trimeric, membrane-anchored protein that has been shown to interact with the p75NTR neurotrophin receptor. In order to determine if the RVG trimeric oligomerization state is required for its binding with p75NTR, different soluble recombinant molecules containing the entire RVG ectodomain (RVGect) were expressed alone or fused at its C terminus to t...
Adenoviral (Ad) vectors have been widely used in human gene therapy clinical trials. However, their application has frequently been restricted by the unfavorable expression of cell surface receptors critical for Ad infection. Infections by Ad2 and Ad5 are largely regulated by the elongated fiber protein that mediates its attachment to a cell surface receptor, coxsackie and adenovirus receptor (...
The first benzene-centered, phthalocyanine hexamer has been synthesized by a dicobaltoctacarbonyl-catalyzed trimerization reaction of an ethynyl-bridged bisphthalocyanine and characterized by different spectrometric and spectroscopic techniques.
the catalytic air oxidation-trimerization of alcohols was carried out with hetropolyacids. in the presence of hetropolyacid formation of cyclotrimers of alcohols and aldol condensation products was observed. the 1,3,5-trioxanes were major and aldol condensation compounds were minor products.
