BACTEROIDES THETAIOTAOMICRON GH84 O-GLCNACASE IN COMPLEX WITH N-BUTYL-THIAZOLINE INHIBITOR

Overview

O-GlcNAcase catalyzes the cleavage of beta-O-linked, 2-acetamido-2-deoxy-beta-d-glucopyranoside (O-GlcNAc) from serine and, threonine residues of post-translationally modified proteins. Two potent, inhibitors of this enzyme are, O-(2-acetamido-2-deoxy-d-glucopyranosylidene)amino-N-phenylcarbamate, (PUGNAc) and, 1,2-dideoxy-2'-methyl-alpha-d-glucopyranoso[2,1-d]-Delta2'-thiazoline, (NAG-thiazoline). Derivatives of these inhibitors differ in their, selectivity for human O-GlcNAcase over the functionally related human, lysosomal beta-hexosamindases, with PUGNAc derivatives showing modest, selectivities and NAG-thiazoline derivatives showing high selectivities., The molecular basis for this difference in selectivities is addressed as, is how well these inhibitors mimic the ...
