== Publication Abstract from PubMed ==
Mannosides in the southern hemisphere: Conformational analysis of enzymatic mannoside hydrolysis informs strategies for enzyme inhibition and inspires solutions to mannoside synthesis. Atomic resolution structures along the reaction coordinate of an inverting alpha-mannosidase show how the enzyme distorts the substrate and transition state. QM/MM calculations reveal how the free energy landscape of isolated alpha-D-mannose is molded on enzyme to only allow one conformationally accessible reaction coordinate.

The reaction coordinate of a bacterial GH47 alpha-mannosidase: a combined quantum mechanical and structural approach.,Thompson AJ, Dabin J, Iglesias-Fernandez J, Ardevol A, Dinev Z, Williams SJ, Bande O, Siriwardena A, Moreland C, Hu TC, Smith DK, Gilbert HJ, Rovira C, Davies GJ Angew Chem Int Ed Engl. 2012 Oct 29;51(44):10997-1001. doi:, 10.1002/anie.201205338.
