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.
