Abstract

Viral RNA-dependent RNA polymerase (RdRp) plays crucial roles in the genomic replication and subgenomic transcription of (BMV), a positive-stranded RNA plant virus. BMV RdRp is a complex of virus-encoded 1a and 2a proteins and some cellular factors, and associates with the endoplasmic reticulum at an infection-specific structure in the cytoplasm of host cells. In this study, we investigate the gross structure of the active BMV RdRp complex using monoclonal antibodies raised against the 1a and 2a proteins. Immunoprecipitation experiments showed that the intermediate region between the N-terminal methyltransferase-like domain and the C-terminal helicase-like domain of 1a protein, and the N terminus region of 2a protein are exposed on the surface of the solubilized RdRp complex. Inhibition assays for membrane-bound RdRp suggested that the intermediate region between the methyltransferase-like and the helicase-like domains of 1a protein is located at the border of the region buried within a membrane structure or with membrane-associated material.
