  • Assessing Mimicry of the Transition State
    View Article Online / Journal Homepage / Table of Contents for this issue PERSPECTIVE www.rsc.org/obc | Organic & Biomolecular Chemistry Glycosidase inhibition: assessing mimicry of the transition state Tracey M. Gloster*a,b and Gideon J. Davies*a Received 5th August 2009, Accepted 30th September 2009 First published as an Advance Article on the web 5th November 2009 DOI: 10.1039/b915870g Glycoside hydrolases, the enzymes responsible for hydrolysis of the glycosidic bond in di-, oligo- and polysaccharides, and glycoconjugates, are ubiquitous in Nature and fundamental to existence. The extreme stability of the glycosidic bond has meant these enzymes have evolved into highly proficient catalysts, with an estimated 1017 fold rate enhancement over the uncatalysed reaction. Such rate enhancements mean that enzymes bind the substrate at the transition state with extraordinary affinity; the dissociation constant for the transition state is predicted to be 10-22 M. Inhibition of glycoside hydrolases has widespread application in the treatment of viral infections, such as influenza and HIV, lysosomal storage disorders, cancer and diabetes. If inhibitors are designed to mimic the transition state, it should be possible to harness some of the transition state affinity, resulting in highly potent and specific drugs. Here we examine a number of glycosidase inhibitors which have been developed over the past half century, either by Nature or synthetically by man. A number of criteria have been proposed to ascertain which of these inhibitors are true transition state mimics, but these features have only be critically investigated in a very few cases. Introduction molecules, lipids or proteins), constitute between 1 and 3% of the genome of most organisms.1 The task facing these enzymes Glycosidases, the enzymes responsible for the breakdown of di-, with respect to maintaining efficient and highly specific catalysis oligo- and polysaccharides, and glyconjugates, are ubiquitous is no mean feat; it has been calculated that there are 1.05 ¥ 1012 through all kingdoms of life.

Thus, it has been reported that laforin and malin form a functional complex that acts as a key regulator of glycogen metabolism and that also plays a crucial role in protein homeostasis (proteostasis). In relationship with this last function, it has been shown that cells are more sensitive to ER-stress and show defects in proteasome and autophagy activities in the absence of a functional laforin-malin complex.
