Effect of UV Light on RNA-Directed DNA Polymerase Activity of Murine Oncornaviruses.

The UV inactivation of RNA-directed DNA polymerase activity of Rauscher leukemia virus was shown to be due to damage to the protein. The UV dose resulting in 37% survival of viral polymerase activity at 254 nm was 2.4 x 10(4) to 3.1 x 10(4) ergs/mm(2). The inactivation rate of p30, a major internal viral protein, was much slower.
