A New Concept for the Mechanism of Action of Chymotrypsin:  The Role of the Low-Barrier Hydrogen Bond

Biochemistry, 1997
The basicities of the diad H57-D102 at N(epsilon)2 in the tetrahedral complexes of chymotrypsin with the peptidyl trifluoromethyl ketones (TFK) N-acetyl-L-Leu-DL-Phe-CF3 and N-acetyl-DL-Phe-CF3 have been studied by 1H-NMR. The protons bridging His 57 and Asp 102 in these complexes are engaged in low-barrier hydrogen bonds (LBHBs).
