title: Hematoporphyrin-sensitized photodynamic inactivation of viral RNA-dependent DNA polymerase.
abstract: Visible light (6328A) was shown to inactivate RNA-dependent DNA polymerase activity of Moloney mouse leukemia virus, in the presence of hematoporphyrin. The same treatment on exogenous, template-initiation complex had no effect on enzyme activity. It was suggested that this enzyme may be the target of photodynamic inactivation of this and related viruses.
