RESUMO
Tryptic peptide maps were prepared for four purified structural proteins derived from several murine leukemia viruses (MuLV's). Analyses of these peptide maps reveal that the p30 proteins of Rauscher, Moloney, and Gross MuLV's are very similar to each other, as are the p10's obtained from these three viruses. In contrast, the peptide maps of the individual p15's and p12's from the same viruses establish that each of these polypeptides is highly strain specific. For all four polypeptides studied, unique peptides appear in the Rauscher MuLV and Moloney MuLV tryptic profiles that are not present in the corresponding Gross MuLV profile. By this method of analysis it was possible to distinguish the p30's of N-tropic and B-tropic MuLV's derived from the same BALB/c mouse.
