The activating effect of Na(+) on thrombin is allosteric and depends on the conformational transition from a low activity Na(+)-free (slow) form to a high activity Na(+)-bound (fast) form. The structures of these active forms have been solved. Recent structures of thrombin obtained in the absence of Na(+) have also documented inactive conformations that presumably exist in equilibrium with the active slow form ...
