... of the second transmembrane α-helix in MscL. The efficiency of hydrophobic matching between MscL and the surrounding lipid bilayer is high. Fluorescence quenching methods can also be used to study binding of lipids to non-annular sites such as those between monomers in the homotetrameric potassium channel KcsA...

... proteins are described. Comparison of simulations of KcsA (an α-helical bundle) and OmpA (a β-barrel) reveals the importance of two classes of side chains in stabilizing interactions with the head groups of lipid molecules: (i) tryptophan and tyrosine; and (ii) arginine and lysine. Arginine residues...
