Activity of type A/B mosaic polymerase machinery with a type A HA segment promoter. Combinations of type A and B components are shown at the bottom. Polymerase activities are quantified by use of a SEAP assay with B/Lee-, or B/Panama-derived components as described in the legend to Fig. 1. As controls, SEAP values for homologous type A (lane 1) and type B (lane 16) polymerase machinery are shown.
