Extracellular self-assembly of virus-like particles from secreted recombinant polyoma virus major coat protein.
Mouse polyoma virus major coat protein (VP1) expressed from a recombinant baculovirus is efficiently transported to infected cell nuclei and assembles into protein nanospheres morphologically similar to natural capsids. The nanospheres readily combine with plasmid DNA to form a hybrid gene therapy agent known as virus-like particles (VLPs). To facilitate large-scale production of VLPs free from...
متن کاملSelf-assembly of nucleocapsid-like particles from recombinant hepatitis C virus core protein.
Little is known about the assembly pathway and structure of hepatitis C virus (HCV) since insufficient quantities of purified virus are available for detailed biophysical and structural studies. Here, we show that bacterially expressed HCV core proteins can efficiently self-assemble in vitro into nucleocapsid-like particles. These particles have a regular, spherical morphology with a modal dist...
متن کاملTriatoma virus structural polyprotein expression, processing and assembly into virus-like particles.
In contrast to the current wealth of structural information concerning dicistrovirus particle structure, very little is known about their morphogenetic pathways. Here, we describe the expression of the two ORFs encoded by the Triatoma virus (TrV) genome. TrV, a member of the Cripavirus genus of the Dicistroviridae family, infects blood-sucking insects belonging to the Triatominae subfamily that...
متن کاملProteolytic processing of sapovirus ORF1 polyprotein.
The genome of Sapovirus (SaV), a causative agent of gastroenteritis in humans and swine, contains either two or three open reading frames (ORFs). Functional motifs characteristic to the 2C-like NTPase (NTPase), VPg, 3C-like protease (Pro), 3D-like RNA-dependent RNA polymerase (Pol), and capsid protein (VP1) are encoded in the ORF1 polyprotein, which is afterwards cleaved into the nonstructural ...
