WebbDuring bacteriophage T7 infection a phage-specified RNA polymerase transcribes the late phage genes in two temporal classes (class II and class III). In this report, we show that the purified phage polymerase discriminates between the class II and class III promoters in vitro as a function of variables that alter the stability of the DNA helix. Webbdemonstrates identical transcription proﬁles using T7 RNA polymerase and Strep-T7 RNA polymerase. This conﬁrms that the addition of the Strep-tag II peptide has no adverse effect on the activity of T7 RNA polymerase. Similarly, biotinylating the upstream end of the promoter has no effect on promoter function, as also shown in Fig. S2.
