Studies on the polypeptides of poxvirus. I. Comparison of structural polypeptides in vaccina, cowpox and Shope fibroma viruses.
Radioactively labeled vaccinia, cowpox and Shope fibroma virions free from any detectable contamination with host cell protein, were dissociated into their constituent polypeptides, and these were then analyzed by SDS-polyacrylamide gel electrophoresis and autoradiography. The profiles of constituent polypeptide bands of four strains of vaccinia virus (IHD-W, IHD-J, Lister and DIs) were almost the same, except that a polypeptide of about 41,000 daltons was not detectable in the autoradiogram of strain IHD-W which has no hemagglutinin. The profile of polypeptide bands of cowpox virions was also almost the same as that of vaccinia virions, except for several polypeptides of about 40,000 to 50,000 daltons, but the profile of Shope fibroma virions differed considerably from that of vaccinia or cowpox virions.
