The activity of PvdS and FpvI in the presence and absence of FpvR 1–89 . β-galactosidase assays were carried out with E. coli MC1061 (DE3) containing either (A) pMP190::PfpvA_lacZ or (B) pMP190::PpvdE_lacZ, along with pETDuet expressing FpvR1–89 and either (A) FpvI or (B) PvdS. An empty pETDuet control is also shown to control for background expression of lacZ from pMP190::PfpvA_lacZ or pMP190::PpvdE_lacZ. Averages were obtained from three biological replicates. Error bars are ±1 SD.
