Localization of polypeptides in frog virus 3 by radioiodination technique

Frog virus 3 is an amphibian icosahedral deoxyribovirus which replicates in the cytoplasm of infected cells. The radioiodination of purified virions using the enzyme lactoperoxidase has shown that the major component of the structural proteins is only partially exposed through the lipoprotein membrane that constitutes the outer layer of the icosahedral capsid.
