== Publication Abstract from PubMed ==
One useful methodology that has been used to give insight into how chemically synthesized inhibitors bind to enzymes and the reasons underlying their potency is crystallographic studies of inhibitor-enzyme complexes. Presented here is the X-ray structural analysis of a representative family 20 exo-beta-N-acetylhexosaminidase in complex with various known classes of inhibitor of these types of enzymes, which highlights how different inhibitor classes can inhibit the same enzyme. This study will aid in the future development of inhibitors of not only exo-beta-N-acetylhexosaminidases but also other types of glycoside hydrolases.

Gaining insight into the inhibition of glycoside hydrolase family 20 exo-beta-N-acetylhexosaminidases using a structural approach.,Sumida T, Stubbs KA, Ito M, Yokoyama S Org Biomol Chem. 2012 Apr 7;10(13):2607-12. Epub 2012 Feb 27. PMID:22367352<ref>PMID:22367352</ref>
