    Single-Molecule Mechanistic Study of Enzyme Hysteresis

    Hysteresis is an important feature of enzyme-catalyzed reactions, as it reflects the influence of enzyme regulation in the presence of ligands such as substrates or allosteric molecules. In typical kinetic studies of enzyme activity, hysteretic behavior is observed as a lag or burst in the time course of the catalyzed reaction.
