Aquaporin-0 (AQP0) tetramers form square arrays in lens membranes through a yet unknown mechanism, but are enriched sphingomyelin and cholesterol. Here, we determined electron crystallographic structures of AQP0 sphingomyelin/cholesterol performed molecular dynamics (MD) simulations to establish that the observed cholesterol positions represent those seen around an isolated tetramer largely defines location orientation most its associated molecules. At high concentration, increases...

Several antimicrobial peptides, including magainin and the human cathelicidin LL‐37, act by forming pores in bacterial membranes. Bacteria such as Staphylococcus aureus modify their membrane's cardiolipin composition to resist types of perturbations that compromise membrane stability. Here, we used molecular dynamic simulations quantify role on formation simple bacterial‐like models composed phosphatidylglycerol mixtures. Cardiolipin modified structure ordering lipid bilayer, making it less...
