Scheme 5. Summary of the Interceptions of the Catalytic Cycle of CODH_Ch I by Small Molecule Inhibitors, As Deduced from PFE Experiments.

The potentials −250 and −50 mV are the values observed for reactivation of enzyme with and without sulfide. The potential −520 mV is the standard potential for the CO₂/CO half-cell reaction at pH 7.0. Reprinted with permission from ref (45b). Copyright 2013 American Chemical Society.
