Chemically-induced redox switching of a metalloprotein reveals thermodynamic and kinetic heterogeneity, one molecule at a time†
Abstract
Oxidation (off state) and reduction (on state) of a single azurin molecule is monitored, one electron at a time, which depend on the chemical redox potential. By analysing the fluorescence time traces from individual azurin molecules, reaction kinetics and redox thermodynamics were determined.
