Inhibitors that bind to the S1 web site block the formation of S1,S2-DAT and hence the translocation. Inhibitors that bind to the S2 site inhibit the release of S1 and act as translocation de-couplers
The binding of a second substrate (doubly occupied condition in green) induces conformational adjustments in the S1 website and the intracellular aspect by means of conserved conversation networks (coloured lozenges)…
