- Abstract
The poliovirus genome-linked protein (VPg) has been subjected to radiochemical microsequence analysis. Sequence studies of virion RNA by a modification of Sanger's dideoxy method have revealed a base sequence corresponding to the amino acid analysis. This result proves that VPg is virus-encoded. The RNA sequence has allowed us to predict the total amino acid sequence of VPg and part of its precursor. VPg is, at most, 27 amino acids long. It maps within the 3' terminal segment of the viral genome that encodes the precursor polypeptide NCVP1b for the virus-specific RNA polymerase NCVP4.
