We have purified two general transcription factors (FA and FE) necessary for specific transcription by mammalian RNA polymerase II to near homogeneity. Both activities are associated with peptides of ≈33 kDa. FA and FE do not replace one another and show different kinetics of action in a sarkosyl block assay. In particular, FE participated in a rapid reaction after the formation of an initial complex with the other transcription factors. Furthermore, FE can associate with purified calf thymus RNA polymerase II.
