  Enhanced diffusion and anti-chemotaxis of enzymes have been reported in
several experiments in the last decade, opening up entirely new avenues of
research in the bio-nanosciences both at the applied and fundamental level.
Here, we introduce a novel theoretical framework, rooted in non-equilibrium
effects characteristic of catalytic cycles, that explains all observations made
so far in this field. In addition, our theory predicts entirely novel effects,
such as dissipation-induced switch between anti-chemotactic and chemotactic
behavior.
