Translational diffusion of Fos-10 micelles (Fos-10) and OmpX-containing Fos-10 micelles (OmpX/Fos-10) in aqueous solution containing detergent concentrations above (Na,pm[IMP] + c.m.c.). The data was aquired using the PFG-STE NMR experiment with observation of Fos-10 1H NMR signals. The circles represent measured apparent translational diffusion coefficients for the Fos-10 micelles,
, (A) and the OmpX-containing Fos-10 micelles
(B) (see text). The solid and broken lines represent model calculations for the situations with [m] = 10 mM and [m] = 16 mM, respectively, where [m] is the concentration of Fos-10 monomers as determined by the effective c.m.c. value in the NMR sample. The system was modeled with the assumption that the exchange between detergent monomers, detergent micelles and OmpX-containing detergent micelles (Figure 1) is fast.
