Filovirus helical nucleocapsid structures

Microscopy, 2022
Abstract Filoviruses are filamentous enveloped viruses belonging to the family Filoviridae, in the order Mononegavirales. Some filovirus members, such as Ebola virus and Marburg virus, cause severe hemorrhagic fever in humans and non-human primates.

The sense of the helix of paramyxovirus nucleocapsids

Journal of Molecular Biology, 1972
Abstract The sense of the helix of the nucleocapsid of the parainfluenza virus SV5 is left-handed, and evidence has been found suggesting that the nucleocapsid of mumps virus is also left-handed.

On the infectivity of the Sindbis virus nucleocapsid

Canadian Journal of Microbiology, 1970
The nucleocapsid fraction derived either from Sindbis virions or from infected cell cultures was studied with respect to its ability to adsorb to susceptible cells as well as to initiate stages in viral replication. Neither preparation was adsorbed to BHK 21 cells under conditions where virion adsorption could be demonstrated. In addition parental RNA

The ultrastructure of disrupted herpesvirus nucleocapsids

Virology, 1975
Abstract Nucleocapsids prepared by treating herpes simplex or varicella-zoster virions with Nonidet P-40 were found to be degraded by EDTA-trypsin. Initial action of the enzyme appeared to be to degrade the pentameric capsomeres located on the vertices of the icosahedron and thus cause the capsid to flatten and the capsomeres to align in a ...

Nucleocapsid Structure and Function

2008
Measles virus belongs to the Paramyxoviridae family within the Mononegavirales order. Its nonsegmented, single-stranded, negative-sense RNA genome is encapsidated by the nucleoprotein (N) to form a helical nucleocapsid. This ribonucleoproteic complex is the substrate for both transcription and replication.

Envelope and nucleocapsid antigens of Cytomegalovirus (CMV)

Medical Microbiology and Immunology, 1975
A method for the purification and concentration of Cytomegalovirus nucleocapsids and particles complete with envelope is described. Antibody to either nucleocapsid or envelope antigens can be detected in human sera. In patients with CMV disease the antibodies to the envelope antigen could not be detected before the 3rd week after the beginning of ...

Mechanisms governing hepadnaviral nucleocapsid assembly

Journal of Hepatology, 1993
Reverse transcription of an RNA pregenome is the central step in the replication cycle of the hepatitis B viruses. This reaction takes place within the viral nucleocapsid composed of the core protein, product(s) of the P (pol) gene and the RNA pregenome.

Isolation and structure of the nucleocapsid of HVJ

Virology, 1968
Abstract A method for isolation of the nucleocapsids of HVJ from virions was developed: HVJ virions suspended in Na 2 CO 3 NaHCO 3 buffer (0.02 M , 1:1) were disintegrated with Emasol 1130 (a Tween 20-like surfactant) and banded by CsCl equilibrium centrifugation. The nucleocapsids of HVJ formed a band at a buoyant density of 1.31, and most of the

Intracellular stability of nonreplicating paramyxovirus nucleocapsids

Virology, 1990
Using Northern blot analysis, we have demonstrated the ability of infectious measles and Sendai virus particles to rescue the intracellular replication of their homologous defective interfering (DI) nucleocapsids up to 3 days and 1 day, respectively, after initial DI infection. The half-life of the paramyxovirus DI nucleocapsids was therefore judged to

Studies on the helical nucleocapsid of influenza virus

Virology, 1982
Abstract A high-resolution electron microscopic study of the structure of the influenza virus nucleocapsid and the effects of salt concentration on conformation has been carried out. The helical nucleocapsid segments are coiled tightly under conditions of low salt and are unwound in high-salt environments.
