Serine protease dynamics revealed by NMR analysis of the thrombin-thrombomodulin complex
Serine proteases catalyze a multi-step covalent catalytic mechanism of peptide bond cleavage. It has long been assumed that serine proteases including thrombin carry-out catalysis without significant conformational rearrangement of their stable two-?-barrel structure. We present nuclear magnetic resonance (NMR) and hydrogen deuterium exchange mass spectrometry (HDX-MS) experiments on the thrombin-thrombomodulin (TM) complex. Thrombin promotes procoagulative fibrinogen cleavage when fibrinogen...

Abstract
The conformational properties *of trypsin-like proteases and their zymogen forms remain controversial because of a lack of sufficient information on their free forms. Specifically, it is...

Oxidation of Met 388, one of the three linker residues connecting the fourth and fifth EGF-like domains of thrombomodulin (TM), is deleterious for TM activity. An NMR structure of the smallest active fragment of TM (TMEGF45) and a crystal structure of a larger fragment (TMEGF456) bound to thrombin...
