pubmed:abstractText |
We have purified two low-molecular-weight polypeptides from the Prague C strain of Rous sarcoma virus and have identified these as products of the gag precursor Pr76 by protein sequencing and by amino acid analysis. Both polypeptides are derived from a stretch of 22 amino acids within Pr76 that separates p19 and p10. We refer to this region as p2. Together the two cleavage products form the entire p2 region. The junctions of p19 with the amino-terminal fragment of p2 and of p10 with the carboxy-terminal fragment of p2 define two new processing sites within the gag precursor, Tyr-155-His-156 and Gly-177-Ser-178. Both polypeptides are major cleavage products of Pr76 that occur in Prague C Rous sarcoma virus at an estimated 1,000 copies per virion. They also are prominent components of avian myeloblastosis virus. The combination of gel filtration and reverse-phase high-pressure liquid chromatography, which was used for the isolation of the two fragments of p2, resolved over a dozen other low-molecular-weight polypeptides from avian sarcoma and leukemia viruses that previously were undetected. This technique thus should serve as a useful procedure for further characterization of viral components.
