The Genome-linked Protein of Picornaviruses. VIII. Complete Amino
... In the results presented here we have conclusively shown the complete primary structure of poliovirus VPg. It is 22 amino acids in length, 2354 Mr, and terminates in -valyl-glutamineCOOH. The nature of the carboxy-terminus did not surprise us since in the poliovirus polyprotein, from which VPg is ul ...
