Fig. 6. The bending rigidity decreases as the proportion of the area occupied by the integral membrane protein BtuB increases for the two component POPE/POPG bilayer. The additional BtuB datapoints come from a published series of coarse-grained simulations of smaller patches of POPE/POPG containing a range of densities of BtuB, OmpF and BtuB + OmpF66 – the results for all three protein combinations are given in Fig. S13 (ESI†). These simulations were analysed (Fig. S9–S12, ESI†) and added to our dataset to improve the statistics. Details of these simulations can be found in Table S2 (ESI†).
