Studies on the structure of the two infectious types of densonucleosis virus.

No electrophoretic differences were detected between the nucleic acids of the two types of densonucleosis virus, DNV-I and DNV-II. Both virus types had similar isoelectric points. Although the viral proteins found in each type were identical, their stoichiometry differed. The localization of the structural protein, by labeling with periodate-oxidized glycoprotein, supported the hypothesis that 60 molecules of p49 aggregated into a dodecahedron (12 pentamers), whereas the two other proteins (p59 and p69) might have a stabilizing function and were localized on the outer surface of the p49 dodecahedron.
