Figure 6

The location of mutations in FpvI and PvdS that increased sigma factor activity in the presence of FpvR 1–89 . The approximate location of mutations are shown on the ECF sigma factor functional regions two (2.1-2.4) and four (4.1 and 4.2) of (A) FpvI and (B) PvdS according to the following classifications: ▲mutation(s) that gave higher activity in the presence, not absence of FpvR1–89; ■ mutation(s) that gave higher activity whether or not FpvR1–89 was present; ● mutation(s) that gave higher activity in the presence of FpvR1–89 and were not tested in the absence of FpvR1–89. Each mutant is represented on a different line.
