Structural polypeptides of the murine coronavirus JHM.
Analysis by SDS-polyacrylamide gel electrophoresis shows that the purified coronavirus JHM contains six polypeptides. The apparent mol. wt. of the polypeptides (GP1, GP2, GP3, VP4, GP5 and VP6) are 170000; 125000; 97500; 60800; 24800 and 22700, respectively. Four polypeptides are glycosylated (GP1, GP2, GP3 and GP5). The analysis of particles obtained after limited proteolysis with pronase sugg...
متن کاملStructural polypeptides of measles virus.
The structural polypeptides of two strains of measles virus grown in Vero cells were analysed in SDS-PAGE slab gels. Six major polypeptides were identified with mol. wt. of 79000, 72000, 60000, 43000, 40000 and 36000. The largest polypeptide was sensitive to trypsin digestion and was the dominant glycosylated polypeptide identified when the virus was grown in medium containing 3H-fucose or 3H-g...
متن کاملCloning and sequencing of the gene encoding the spike protein of the coronavirus IBV.
RNA sequences encoding the surface projection (spike) of the coronavirus infectious bronchitis virus, strain Beaudette, have been cloned into pBR322 using cDNA primed with a specific oligonucleotide. A 5.3 kilobase viral insert in the clone pMB179 has been identified. The region of this clone coding for the spike gene has been sequenced by the chain termination method, and we present here the f...
متن کاملStructural polypeptides of Hazara virus.
Four structural polypeptides of Hazara virus, an agent closely related to the Crimean-Congo haemorrhagic fever (C-CHF) viruses, were resolved by SDS-polyacrylamide gel electrophoresis. Three glycoproteins were identified (mol. wt. 84,000, 45,000 and 30,000) and were found to be associated with the virion envelope. A fourth polypeptide (mol. wt. 52,000) was non-glycosylated and associated with t...
متن کاملBovine coronavirus structural proteins.
The tissue culture-adapted strain (Mebus) of bovine coronavirus was grown in the presence of isotopically labeled amino acids, glucosamine, or orthophosphate for the purpose of analyzing the virion structural proteins. Five species of polypeptides were identified when purified virions were solubilized in urea and sodium dodecyl sulfate and resolved by polyacrylamide gel electrophoresis. Four sp...
