Role of intermolecular interactions of vesicular stomatitis virus nucleoprotein in RNA encapsidation.
The crystal structure of the vesicular stomatitis virus nucleoprotein (N) in complex with RNA reveals extensive and specific intermolecular interactions among the N molecules in the 10-member oligomer. What roles these interactions play in encapsidating RNA was studied by mutagenesis of the N protein. Three N mutants intended for disruption of the intermolecular interactions were designed and c...
متن کاملStructure and Function of the N-Terminal Domain of the Vesicular Stomatitis Virus RNA Polymerase.
UNLABELLED Viruses have various mechanisms to duplicate their genomes and produce virus-specific mRNAs. Negative-strand RNA viruses encode their own polymerases to perform each of these processes. For the nonsegmented negative-strand RNA viruses, the polymerase is comprised of the large polymerase subunit (L) and the phosphoprotein (P). L proteins from members of the Rhabdoviridae, Paramyxoviri...
متن کاملMorphogenesis of the nucleoprotein of vesicular stomatitis virus.
Accumulation of the nucleoprotein of vesicular stomatitis virus (VSV) in the cytoplasm of BHK-21 cells and in two of four human cell lines was demonstrated. Appearance and progression of the nucleoprotein inclusions paralleled development of virus-specific immunofluorescence and production of virus progeny. The inclusions appeared early as discrete foci of filamentous material which eventually ...
متن کاملResidues within the N-terminal domain of human topoisomerase I play a direct role in relaxation.
All eukaryotic forms of DNA topoisomerase I contain an extensive and highly charged N-terminal domain. This domain contains several nuclear localization sequences and is essential for in vivo function of the enzyme. However, so far no direct function of the N-terminal domain in the in vitro topoisomerase I reaction has been reported. In this study we have compared the in vitro activities of a t...
متن کاملKernel energy method applied to vesicular stomatitis virus nucleoprotein.
The kernel energy method (KEM) is applied to the vesicular stomatitis virus (VSV) nucleoprotein (PDB ID code 2QVJ). The calculations employ atomic coordinates from the crystal structure at 2.8-A resolution, except for the hydrogen atoms, whose positions were modeled by using the computer program HYPERCHEM. The calculated KEM ab initio limited basis Hartree-Fock energy for the full 33,175 atom m...
