RESUMO
Translation of in vitro-synthesized herpes simplex virus type 2 (HSV-2) gG-2 mRNA in a reticulocyte lysate system was used to study the processing of HSV-2 gG-2. In the presence of canine pancreatic microsomal membranes, a single species that is protected from trypsin digestion was detected. This product comigrates with the 104,000-Mr (104K) high mannose intermediate seen in HSV-2-infected-cell lysates. Endo-beta-N-acetylglucosaminidase H treatment of the in vitro-synthesized 104K protein yielded a single product migrating at 100 K. The 72K and 31K cleavage products of gG-2 were not observed in the in vitro system. These data show that the molecular weight of the nonglycosylated form of the gG-2 protein is 100,000 and that the cotranslational processing of this protein in the endoplasmic reticulum yields the 104K high-mannose intermediate.
