Table 3 β-glucuronidase activity promoted by the regulatory regions of flgE2p, fliF2p, flgB2p, fliL2p, and fliI2pa

From: Architecture of divergent flagellar promoters controlled by CtrA in Rhodobacter sphaeroides

  WT ΔctrA
flgE2p 148 ± 32 1.4 ± 0.36
fliF2p 166 ± 27 1.0 ± 0.24
flgB2p 125 ± 24 0.52 ± 0.12
flgL2p 204 ± 36 0.28 ± 0.06
fliI2p 99 ± 19 0.37 ± 0.09
  1. aThe plasmids pRK415/uidA carrying the indicated regulatory regions were introduced to AM1 (WT) and EA1 (ΔctrA) and the amount of β-glucuronidase was determined. Activity is expressed as μmol of 4-methyl-umblliferone/min/mg of protein. The values represent an average of three independent experiments
