Abstract

By the use of strong denaturing agents, a genome-linked protein (VPg)-RNA complex was purified from infectious pancreatic necrosis virus. Ribonuclease treatment of I-labelled VPg-RNA released a 90K polypeptide identical to the minor structural polypeptide VP1 (the putative RNA polymerase), as determined by peptide mapping. The polypeptide is linked to the RNA by a serine-5′ GMP phosphodiester bond. The results identify birnaviruses as the only dsRNA viruses with a VPg, the size of which is the largest of the VPgs of RNA viruses.
