@article{Biddle2019ReversalSF, title={Reversal symmetries for cyclic paths away from thermodynamic equilibrium.}, author={John W. Biddle and Jeremy Gunawardena}, journal={Physical review. E}, year={2019}, volume={101 6-1}, pages={ 062125 } }

If a system is at thermodynamic equilibrium, an observer cannot tell whether a film of it is being played forward or in reverse: any transition will occur with the same frequency in the forward as in the reverse direction. However, if expenditure of energy changes the rate of even a single transition to yield a nonequilibrium steady state, such time-reversal symmetry undergoes a widespread breakdown, far beyond the point at which the energy is expended. An explosion of interdependency also…

This study studied the single-molecule enzyme dynamics of horseradish peroxidase with dihydrorhodamine 123 and hydrogen peroxide as substrates and identified nonequilibrium flux as the origin of such non-Michaelis–Menten enzyme rate behavior, and provided a framework for experimentally quantifying the dynamic and thermodynamic driving forces.
