Abstract: Nanopores have been used to detect molecules, to sequence DNA, or to investigate chemical reactions at the single-molecule level. Because they approach the absolute limit of sensor miniaturization, nanopores are amenable to parallelization and could be used in single-cell measurements. Here we show that single enzymes can be functionally and reversibly trapped inside the confined space of a ClyA nanopore. Remarkably, the binding of ligands to the internalized proteins is mirrored by specific changes to the nanopore conductance. Conveniently, the manipulation of the charge of the protein allowed increasing of the residence time of the
protein inside the nanopore. Nanopores with internalized protein adaptors can be used to study proteins in real time or can be incorporated into inexpensive portable devices for the detection of analytes with high selectivity.
