Cell-free synthesis of herpes simplex virus proteins

Abstract

Polyribosomes isolated from herpes simplex virus type I (HSV-1)-infected cells have been used to program a eucaryotic cell-free translation system. At least 10 HSV-specific polypeptides, with apparent molecular weights of 25,000 to 160,000, are synthesized by wild-type HSV-infected polyribosomes. Polyribosomes prepared from thymidine kinase-negative mutants of HSV direct the synthesis of three putative nonsense termination polypeptides. HSV-specific polypeptides synthesized in vitro are precipitated with antiserum to HSV-infected cell proteins.
