RESUMO

The genome of MG virus, a variant of the human papovavirus BK virus, consists of two molecules, M1 and M2, M1 and M2 have deletions which correspond to 0.33 to 0.55 map unit and 0.77 to 0.85 map unit, respectively, from the EcoRI site on the BK virus genome. Restriction enzyme analysis of the DNAs of these viruses revealed many alterations in both DNA species. Both M1 and M2 DNAs have three recognition sites for EcoRI. M1 has a single recognition site for HindIII and five sites for PvuII. M2 has a single recognition site for PuvII and three sites for HindIII. The sites of these and several other restriction enzymes on each DNA molecule were mapped after the cloning of M1 and M2 DNAs into pBR322 at their unique HindIII and PvuII sites, respectively.
