BETA-GLUCOSIDASE FROM THERMOTOGA MARITIMA IN COMPLEX WITH PHENETHYL-SUBSTITUTED GLUCOIMIDAZOLE
OverviewOverview
Inhibition of glycosidases has great potential in the quest for highly, potent and specific drugs to treat diseases such as diabetes, cancer, and, viral infections. One of the most effective ways of designing such, compounds is by mimicking the transition state. Here we describe the, structural, kinetic, and thermodynamic dissection of binding of two, glucoimidazole-derived compounds, which are among the most potent, glycosidase inhibitors reported to date, with two family 1, beta-glycosidases. Provocatively, while inclusion of the phenethyl moiety, improves binding by a factor of 20-80-fold, this does not appear to result, from better noncovalent interactions with the enzyme; instead, improved, affinity may be derived from significantly better entropic contributions, to binding displayed by the phenethyl-substituted imidazole compound.
