Synthesis of polynucleotide 5'-triphosphatase in vaccinia virus-infected HeLa cells.

abstract：:Nucleocapsid assembly in hepadnavirus replication requires selective encapsidation of the pregenomic RNA template and the viral polymerase by the core proteins. It has been shown that an encapsidation signal located at the 5' end of the pregenomic RNA is responsible for its interaction with the polymerase. In the pres...
