Varicella-zoster virus-induced DNA polymerase.
Nuclear extracts of varicella-zoster virus (VZV)-infected human embryo lung (HEL) cells were found to contain DNA polymerase activity not present in uninfected HEL cells. This enzyme was designated the VZV-induced DNA polymerase. The VZV-induced polymerase was partially separated from the cellular alpha- and beta-polymerases by fractionation of the cells and by phosphocellulose chromatography. The separated enzymes were examined for the effect of added (NH4)2SO4, activity with synthetic templates, optimal pH, and the effect of phosphonoacetic acid. The VZV-induced DNA polymerase was distinct from cellular enzymes and had the properties of a typical herpesvirus-induced DNA polymerase.
