Abstract

Proteases play diverse roles in a variety of essential biological processes, both as non-specific catalysts of protein degradation and as highly specific agents that control physiologic events. Here, we review the mechanisms of substrate specificity employed by serine proteases and focus our discussion on coagulation proteases. We dissect the interplay between active site and exosite specificity and how substrate recognition is regulated allosterically by Na+ binding. We also draw attention to a functional polarity that exists in the serine protease fold, which sheds light on the structural linkages between the active site and exosites.

Warum dies für die Hirudotherapie relevant ist

This review examines mechanisms of substrate specificity employed by serine proteases, focusing on coagulation proteases and dissecting the interplay between active-site and exosite specificity, how substrate recognition is regulated allosterically by Na+ binding, and functional polarity in the protease fold that links the active site to exosites. The work provides a conceptual framework for understanding how coagulation enzymes achieve substrate selectivity through coordinated structural features. CAVEAT: The abstract does not mention hirudin, leeches, or any leech-derived anticoagulant, nor does it single out thrombin by name; this is a general review of coagulation protease biology with no defensible leech link to ASH's domain.
