The large variety of serine protease inhibitors, available from various sources such as tissues, microorganisms, plants, etc., play an important role in regulating the proteolytic enzymes. The analysis of protease-inhibitor complexes helps in understanding the mechanism of action, as well as in designing inhibitors. Vasopressin, an anti-diuretic nonapeptide hormone, is found to be an effective inhibitor of trypsin, with a K(i) value of 5 nM. The crystal structure of the trypsin-vasopressin complex revealed that vasopressin fulfils all the important interactions for an inhibitor, without any break in the scissile peptide bond. The cyclic nature due to a disulfide bridge between Cys1 and Cys6 of vasopressin provides structural rigidity to the peptide hormone. The trypsin-binding site is located at the C terminus, while the neurophysin-binding site is at the N terminus of vasopressin. This study will assist in designing new peptide inhibitors. This study suggests that vasopressin inhibition of trypsin may have unexplored biological implications.
