External small‐molecule triggers were used to reversibly control dynamic protein–ligand interactions in giant vesicles. An alcohol dehydrogenase was employed to increase or decrease the interior pH upon conversion of two different small‐molecule substrates, thereby modulating the pH‐sensitive interaction between a Ni‐NTA ligand on the vesicle membrane and an oligohistidine‐tagged protein in the lumen. By alternating the small‐molecule substrates the interaction could be reversed.
