Novel Allosteric Inhibitors Of Thrombin, Bijoy Desai

Theses and Dissertations

Thrombin is a critical enzyme involved in blood coagulation and haemostasis. For this reason the study of its interactions with substrates, inhibitors and modulator is essential. It is also a unique enzyme in the serine protease family because unlike enzymes like trypsin and chymotrypsin its activity is modulated by various endogenous and exogenous ligands. This is due to the presence of “exosites” on the thrombin surface. Exosite II, unlike exosite-I, has not been characterized for its allosteric effect. In order to understand the structural basis of interaction and inhibition of inhibitor 4AS, which possibly interacts with exosite-II, native bovine thrombin …
