From: Statistically derived asymmetric membrane potentials from α-helical and β-barrel membrane proteins

Raw counts (dashed lines) and fits (solid lines) for amino acid occurrences in β-barrel and α-helical membrane proteins. The cytoplasmic/periplasmic side is at negative numbers along the membrane normal. Each fit includes lipid-accessible and lipid-inaccessible residues (see Supplementary Figs. S1 and S2). Fitting parameters are given in Supplementary Tables 2 and 3.
