Transmissible gastroenteritis coronavirus RNA-dependent RNA polymerase and nonstructural proteins 2, 3, and 8 are incorporated into viral particles.

چکیده
Coronavirus replication and transcription are processes mediated by a protein complex, with the RNA-dependent RNA polymerase (RdRp) as a main component. Proteomic analysis of highly purified transmissible gastroenteritis virus showed the RdRp to be a component of the viral particles. This finding was confirmed by Western blotting, immunofluorescence, and immunoelectron microscopy analyses. Interestingly, the replicase nonstructural proteins 2, 3, and 8 colocalized with the RdRp in the viral factories and were also incorporated into the virions.

The making of infectious viral RNA: No size limit in sight.
D the disadvantage of having an RNA genome, which is more difficult than DNA to be genetically tinkered, the reverse genetics of RNA viruses actually originated at about the same time as the dawning of the genomic manipulation of DNA viruses. The first RNA virus to be genetically modified was Qb phage (1). Initially, the RNA molecules were chemically modified during RNA replication in vitro; th...
متن کاملReplication and packaging of Norwalk virus RNA in cultured mammalian cells.
Human noroviruses, the most common cause of nonbacterial gastroenteritis, are characterized by high infectivity rate, low infectious dose, and unusually high stability outside the host. However, human norovirus research is hindered by the lack of a cell culture system and a small animal model of infection. Norwalk virus (NV) is the prototype strain of human noroviruses. We report here replicati...
متن کاملSequence comparison of the 5' end of mRNA 3 from transmissible gastroenteritis virus and porcine respiratory coronavirus.
Analysis of porcine transmissible gastroenteritis virus (TGEV) and porcine respiratory coronavirus (PRCV) mRNA species indicated a deletion in mRNA 3 of PRCV. Polymerase chain reaction (PCR) was used to clone the 5' end of mRNA 3 from PRCV for comparison with the equivalent region in TGEV. Small deletions were observed within and around the PRCV sequence equivalent to the putative open reading ...

Coronavirus Disease 2019 (COVID-19) is a viral pneumonia emerged in December 2019 in Wuhan, China. Its cause is a new virus from the coronavirus family scientifically named Coronavirus Acute Respiratory Syndrome 2 (SARS-CoV-2). In this review study, articles published in English until March 23, 2020 on new coronavirus infection were reviewed. These articles are obtained by searching in PubMed, ...
متن کاملDifferential Sensitivity of Bat Cells to Infection by Enveloped RNA Viruses: Coronaviruses, Paramyxoviruses, Filoviruses, and Influenza Viruses
Bats (Chiroptera) host major human pathogenic viruses including corona-, paramyxo, rhabdo- and filoviruses. We analyzed six different cell lines from either Yinpterochiroptera (including African flying foxes and a rhinolophid bat) or Yangochiroptera (genera Carollia and Tadarida) for susceptibility to infection by different enveloped RNA viruses. None of the cells were sensitive to infection by...
