Abstract
Herpes simplex virus mutants with single substitutions that decrease DNA binding by the DNA polymerase processivity subunit UL42 are only modestly impaired for viral replication. In this study, recombinant viruses harboring two or four of these mutations were constructed. The more substitutions, the more severe the defects in viral replication and DNA synthesis, suggesting that DNA binding by UL42 is important for these processes.
