Figure 10

Average number of hydrogen bonds between the N-terminus and Trp14 with lipid phosphate and ester groups. The bar plots show the average number of hydrogen bonds per frame for the simulation sets H (left side) and V (right side). The number of hydrogen bonds in each frame of the final 400 ns of each replicate simulation was calculated with the GROMACS tool gmx hbond. The average number of hydrogen bonds per frame was then calculated for each replicate and the average over all the replicates was computed and is displayed in the bar plots. The error bars were calculated using a bootstrap method: for each condition, five new values were resampled with replacement from the original set of five replicates and their mean value was computed, this process was repeated 1000 times and the error was calculated as the standard deviation of these 1000 mean values.
