Using a combination of theory and simulations, we address the following questions: (i) How does token binding kinetics affect the current-density relation on the lattice? (ii) How does this current-density relation depend on the scarcity of tokens? (iii) How do tokens propagate the effects of the locally imposed disorder (such as a slow site) over the entire lattice? (iv) How does a shared pool of tokens couple concurrent TASEPs running on multiple lattices? and (v) How do our results translate to TASEPs with open boundaries that exchange particles with the reservoir? Since real particle motion (including in biological systems that inspired the standard TASEP model, e.g., protein synthesis or movement of molecular motors) is often catalyzed, regulated, actuated, or otherwise mediated, the token-driven TASEP dynamics analyzed in this paper should allow for a better understanding of real systems and enable a closer match between TASEP theory and experimental observations. https://research-explorer.ista.ac.at/download/19785/19787/2025_PhysRevE_Kavcic.pdf application/pdfno American Physical Society2025 eng 2470-0045 2470-0053 00149641560000710.1103/physreve.111.054122 1115 https://research-explorer.ista.ac.at/record/19658 Kavcic, B., &#38; Tkačik, G.
