Activity of type A/B mosaic polymerase machinery, containing type A PA and the other components from type B, with a type A HA segment promoters Combinations of type B components from B/Panama or B/Lee are shown at the bottom. Polymerase activities are quantified by use of a SEAP assay as described in the legend to Fig. 1. As controls, SEAP values for homologous type A (lane 1) and type B (lane 2 for B/Panama and lane 3 for B/Lee) polymerase machinery are shown.
