Primary structure and location of the genome‐linked protein (VPg) of grapevine fanleaf nepovirus

摘要

>The genome linked protein VPg covalently linked to the RNAs of grapevine fanleaf nepovirus has been sequenced. The VPg (M _r=2931) composed of 24 residues is linked by its N-terminal Ser β-OH group to the viral RNAs. The VPg mapped from residues 1218 to 1241 of the 253K polyprotein encoded by GFLV RNA1.
