Fig. 6. Kinetics of FimCHis dissociation from different chaperone-subunit complexes at 37 °C.
For determination of the FimCHis dissociation rate constant (koff), 4 µM of FimCHisI (a), FimCHisIA (b), FimCHisFt (c) or FimCHisFG (d) were incubated with a 9-fold molar excess of FimC. Relaxation to the new equilibrium was monitored by analytical cation exchange chromatography. Solid lines are fits according to a single-exponential function. Source data are provided as a Source Data file.
