(a) Schematic detailing the assembly process of surface-tethered BamA(L7H9)BCDE/POPC sensor surfaces. (b) QCM-D data following the assembly procedure. (c) PNR data (points) and fits (lines) corresponding to D2O solution contrast with both spin-up (↑) and spin-down (↓) magnetic contrasts for the functionalized gold substrates before hBamA(L7H9)BCDE adsorption (blue), after the adsorption of hBamA(L7H9)BCDE within β-OG micelles (green) and upon reconstitution of hBamA(L7H9)BCDE within a POPC bilayer (blue). (d) SLD profiles of the complete interface throughout the assembly process of a hBamA(L7H9)BCDE/POPC proteomembrane, derived from fits to NR data shown in (c and e). SLD profile of the functionalized gold/water interface derived from fits shown in (c). Shaded regions represent 95% confidence intervals determined from MCMC resampling of the experimental data fits.
