Evidence that the nuclease activities associated with the herpes simplex type 1 DNA polymerase are due to the 3'-5' exonuclease.

RESUMO

We investigated nuclease activities associated with the catalytic subunit of herpes simplex virus type 1 DNA polymerase. We confirm that a 3'-5' exonuclease copurifies with this enzyme. Previous reports suggested that a 5' DNase was intrinsic to the polymerase. Our preparation lacks such activity.
