mVDAC-1 β-barrel deformations. (A) Changes of the barrel area (mean ± SE) as a function of the voltage and lipid composition. Each colored curve represents the area change for one of three barrel slices, depicted by the cartoon cylinder inset. (B) Changes of ellipticity ($\left(a-b\right)/a$, where $a>b$ are the ellipse axes) ± SE as a function of the voltage for the same barrel slices as in (A). In both (A) and (B), the dashed lines indicate the plots for PC lipids. To see this figure in color, go online.
