Abstract:
We have purified and characterized Pseudorabies virus (PRV) DNA polymerase from infected TK- mouse cells. PRV DNA polymerase has a 3'->5' exonuclease activity; it is stimulated by ionic strength, requires magnesium for optimal activity and it is more sensitive to aphidicolin than eukaryotic and HSV-1 replicative DNA polymerases. Aphidicolin inhibits in vitro PRV DNA polymerase competitively with respect to dCTP with a Ki of 0.06μM and completely blocks viral growth in vivo at 4.4μM. The high sensitivity to aphidicolin of animal herpesvirus DNA polymerases might allow a topical use of this drug in the a treatment of animal herpesvirus keratitis and stomatitis.
