Use of suppressor analysis to identify DNA polymerase mutations in herpes simplex virus which affect deoxynucleoside triphosphate substrate specificity.

Abstract excerpt

Herpes simplex virus DNA polymerase mutations which map in the N-terminal part of the protein and appear to alter deoxynucleoside triphosphate (dNTP) substrate specificity are described. These mutations suppress a drug hypersensitivity associated with the downstream mutation, Aphr10. We suggest that the mutant residues form part of the dNTP-binding site, a site previously thought to be confined to the C terminus.
