Selection of distance cutoffs for PyLipID analysis. (A) Minimum distance between AA headgroup bead and sidechain of any interacting residue over a 30 µs simulation. Contacts start at ∼4.1 Å and peak at 5 Å. (B) Number of detected binding sites (based on PyLipID software network analysis) as a product of selected cut-off pairs, with cut-off pairs shown on the x-axis as (lower, upper). Any pair with a lower cutoff of 4.75 Å yielded the largest number of detected binding sites.
