Key residues act as a plug to prevent premature proton flow. The plug is in the periplasm just C-terminal to the MotB TM, consisting of an amphipathic alpha helix flanked by Pro-52 and Pro-65, eg in Swiss:D3V2T1. In addition to the Pro residues, Ile-58, Tyr-61, and Phe 62 are also essential for plug function [1][2].
