The epidemic of severe acute respiratory syndrome (SARS) was caused by a newly emerged coronavirus (SARS-CoV). Bats of several species in southern People's Republic of China harbor SARS-like CoVs and may be reservoir hosts for them. To determine whether bats in North America also harbor coronaviruses, we used reverse transcription-PCR to detect coronavirus RNA in bats. We found coronavirus RNA ...
The severe acute respiratory syndrome coronavirus (SARS-CoV) nonstructural proteins nsp1 to nsp16 have been implicated by genetic analysis in the assembly of a functional replication/transcription complex. We report the crystal structure of nsp10 from SARS-CoV at 2.1-A resolution. The nsp10 structure has a novel fold, and 12 identical subunits assemble to form a unique spherical dodecameric arc...
Coronaviruses have the potential to cause significant economic, agricultural and health problems. The severe acute respiratory syndrome (SARS) associated coronavirus outbreak in late 2002, early 2003 called attention to the potential damage that coronaviruses could cause in the human population. The ensuing research has enlightened many to the molecular biology of coronaviruses. A programmed -1...

The pathogenesis of SARS coronavirus (CoV) remains poorly understood. In the current study, two recombinant baculovirus were generated to express the spike (S) protein of SARS-like coronavirus (SL-CoV) isolated from bats (vAcBS) and the envelope (E) and membrane (M) proteins of SARS-CoV, respectively. Co-infection of insect cells with these two recombinant baculoviruses led to self-assembly of ...
Formation of the coronavirus replication-transcription complex involves the synthesis of large polyprotein precursors that are extensively processed by virus-encoded cysteine proteases. In this study, the coding sequence of the feline infectious peritonitis virus (FIPV) main protease, 3CL(pro), was determined. Comparative sequence analyses revealed that FIPV 3CL(pro) and other coronavirus main ...
In November 2002, an outbreak of a life-threatening ‘atypical pneumonia’ for which no etiological agent could be identified occurred in Guangdong Province, China. In March 2003, a similar outbreak was reported in Hong Kong [1]. Cases of similar respiratory illness were subsequently reported globally including China, Taiwan, Singapore, Vietnam, Canada and USA. This syndrome is a new clinical ent...
Severe acute respiratory syndrome (SARS) was first described during a 2002-2003 global outbreak of severe pneumonia associated with human deaths and person-to-person disease transmission. The etiologic agent was initially identified as a coronavirus by thin-section electron microscopic examination of a virus isolate. Virions were spherical, 78 nm in mean diameter, and composed of a helical nucl...
http://www.revistadechimie.ro 1055 Feline infectious peritonitis (FIP) is viral, lethal disease caused by a feline coronavirus, with immune-mediated mechanism. The disease has been reported in a variety of species, mountain lion (Felis concolor), caracal (Caracal caracal), lion (Panthera Leo), tiger (Panthera tigris), jaguar (Panthera onca), sand cat (Margarita felis), shaving ( Lynx lynx) and ...
The coronavirus assembly process encloses a ribonucleoprotein genome into vesicles containing the lipid-embedded proteins S (spike), E (envelope), and M (membrane). This process depends on interactions with membranes that may involve palmitoylation, a common posttranslational lipidation of cysteine residues. To determine whether specific palmitoylations influence coronavirus assembly, we introd...
