| Abstract: | The three polyoma virus capsid proteins VP1, VP2, and VP3 were synthesized in vitro in the presence of several radiolabeled amino acids and, after purification on sodium dodecyl sulfate-polyacrylamide gels, were subjected to sequential Edman degradation. The partial amino-terminal amino acid sequences obtained were compared with the sequence of amino acids predicted from the polyoma virus DNA sequencing (Arrand et al., J. Virol. 33:606--618, 1980). Together, these results showed that the 5' ends of the VP1, VP2, and VP3 coding sequences are located 1,217, 289, and 634 nucleotides, respectively, from the junction of HpaII restriction fragments 3 and 5. |
