title: Characterization of intracellular precursor polyproteins of Moloney murine leukemia virus.
abstract: Intracellular Moloney murine leukemia viral precursor polyproteins were compared with mature viral proteins by immunoprecipitation and tryptic peptide mapping experiments. The results were consistent with precursor roles for Pr65gag, Pr200gag-pol, Pr135pol, and gPr83env. The glycosylated gag gene product gPr85gag, although containing sequences characteristic of all four core proteins plus additional sequences not found in Pr65gag, lacked a major tyrosine-containing p30 tryptic peptide, suggesting that gPr85gag is not processed to p30.
