Table 2.

Protein diffusion in solution after dilution below surfactant cmc

Protein RLit (nm) D (μm2 s−1) R (nm)
KcsA 1.2 280 (± 7) 0.8
EcClC 1.8 120 (± 3) 1.9
AcrB 2.1 107 (± 6) 2.1

The radii, R, were calculated using the Stokes-Einstein equation for three-dimensional diffusion with T = 295 K and μ22°C = 0.96 mPa·s for the aqueous PBS buffer. The literature values, RLit, were taken from the respective crystal structures.
