Antithrombin is a natural inhibitor of many serine proteases and it contains an exposed inhibitory loop to intrude the catalytic site of proteases. The peptide bond between R393-S394 (shown as the sphere model in figure 1) plays a critical role in the inhibitory binding. However, the exposure of the inhibitory loop requires a conformational change during activation. In the latent state of antithrombin, this loop is fully buried in the four-strands beta sheet to form a new five-strands beta sheet. This remarkable conformational change of inhibitory loop highlights the activation mechanism of latent antithrombin. The figure below shows the process of the activation of antithrombin.
