Phosphatidylethanolamine (PE) and phosphatidylglycerol (PG) are the main lipid components of the inner bacterial membrane. A computer model for such a membrane was built of palmitoyloleoyl PE (POPE) and palmitoyloleoyl PG (POPG) in the proportion 3:1, and sodium ions (Na+) to neutralize the net negative charge on each POPG (POPE-POPG bilayer). The bilayer was simulated for 25 ns. A final 10-ns trajectory fragment was used for analyses. In the bilayer interfacial region, POPEs and POPGs interact… CONTINUE READING
