Virion-associated transcriptase activity of influenza recombinant and mutant strains.


A comparative study of the in vitro reaction kinetics of the virion RNA polymerase of influenza A strains WS and WSN was conducted to establish phenotypic differences for enzyme activity that might be exchanged as genetic markers among recombinants of these viruses. Characteristically, the RNA polymerase activity of WS virus showed an initial rate of… (More)
