Kinetic studies of WT PgpB (left panels) and R201A variant (right panels). (A) The C55-PP phosphatase activity was measured as a function of the bulk concentration of substrate but no saturation phenomenon was observed in the range of concentrations that could be tested. (B) The C55-PP phosphatase activity was measured with a fixed concentration of substrate (50 µM) but various concentrations of DDM to reflect the dilution of [14C]C55-PP at the micellar surface, and the results are expressed as a function of the C55-PP/DDM mole ratio (mol%). The replot of 1/v versus the reciprocal of the C55-PP/DDM mole ratio is also represented.
