Abstract

We identified a protein which is covalently linked to a fraction of the DNA synthesized in cells infected with minute virus of mice. This protein is specifically bound to the 5' terminus of the extended terminal conformers of the minute virus of mice replicative-form DNA species and of a variable fraction of single-stranded viral DNA. The chemical stability of the protein-DNA linkage is characteristic of a phosphodiester bond between a tyrosine residue in the protein and the 5' end of the DNA. The terminal protein (TP) bound on all DNA forms has a relative molecular weight of 60,000; it is also seen free in extracts from infected cells. Immunologic comparison of the TP with the other known viral proteins suggests that the TP is not related to the capsid proteins or NS-1.
