Differential effect of nucleotide substitutions in the 3' arm of the influenza A virus vRNA promoter on transcription/replication by avian and human polymerase complexes is related to the nature of PB2 amino acid 627.

Abstract excerpt

Using a genetic system that allows the in vivo reconstitution of active ribonucleoproteins, the ability to ensure transcription/replication of a viral-like reporter RNA harboring the G(3) --> A(3), U(5) --> C(5), and C(8) --> U(8) mutations (triple 3-5-8 mutations) in the 3' arm of the promoter w...
