Origin of polyoma virus-associated endonuclease
Abstract
Polyoma virus particles purified from infected cells, but not from the culture medium, exhibited an endonuclease activity distinct from the serum contaminant recently described. This endonuclease cleaved form I polyoma DNA once only per molecule, at one of three possible sites corresponding to the known adenosine-ribosylthymine-rich regions of the molecule.
