The complete nucleotide sequence of gene 3 of pneumonia virus of mice has been determined, and the 5' end of the mRNA mapped using a modification of the polymerase chain reaction technique. The gene contains a single open reading frame, beginning with a 5'-proximal AUG initiation codon, encoding a polypeptide with a predicted Mr of 43141. Expression of the gene 3 protein in Escherichia coli and...

All Sindbis virus temperature-sensitive mutants defective in "late" functions were systematically surveyed by acrylamide-gel electrophoresis for similarities and differences in the intracellular pattern of virus-specific proteins synthesized at the permissive and nonpermissive temperatures. Only cells infected with mutants of complementation group C showed an altered pattern. At the nonpermissi...

Bunyaviruses replicate in the cytoplasm of infected cells. New viral particles are formed by budding of nucleocapsids into the Golgi apparatus. We have previously shown that the IFN-induced human MxA protein inhibits bunyavirus replication by an unknown mechanism. Here we demonstrate that MxA binds to the nucleocapsid protein of La Crosse virus (LACV) and colocalizes with the viral protein in c...

Helical nucleocapsids of each of the paramyxoviruses simian virus 5 (SV5), Newcastle disease virus (NDV), and Sendai virus have been isolated in two different forms. One form contains larger protein subunits and is obtained from mature virions or infected cells dispersed by ethylenediaminetetraacetic acid. The other form possesses smaller subunits and is obtained from infected cells dispersed b...

The template for transcription and replication of negative-stranded RNA viruses is a ribonucleoprotein structure, the nucleocapsid. We have developed a system that supports assembly of the negative-stranded RNA genome of a defective interfering (DI) particle of vesicular stomatitis virus (VSV) into a nucleocapsid in vitro. This system uses extracts from wild-type VSV-infected cells as a source ...

SARS-CoV-2 remains life-threatening human pathogen witnessed in the present world. Purpose. The key objective of this research was to incorporate a bioinformatics technique forecast molecular docking ACE2-associated SARS-CoVs nucleocapsid protein. Methods. Different tools were used study order compare chemical structures with their biological behaviour at levels atoms and ligand-binding affinit...
