Inhibitors of human neuraminidase enzymes (NEU) are recognized as important tools for the study of the biological functions of NEU and will be potent tools for elucidating the role of these enzymes in regulating the repertoire of cellular glycans. Here we report the discovery of selective...

Human neuraminidases (NEU) are associated with human diseases including cancer, atherosclerosis, and diabetes. To obtain small molecule inhibitors as research tools for the study of their biological functions, we designed a library of 2-deoxy-2,3-didehydro-N-acetylneuraminic acid (DANA) analogues...

Structural basis for antibody recognition in the receptor-binding domains of toxins A and B from Clostridium difficile
Download2014
Ng, Kenneth K. S., Tanha, Jamshid, Kitova, Elena N., Eugenio, Luiz, Murase, Tomohiko, Klassen, John S., Hussack, Greg, Schorr, Melissa
Clostridium difficile infection is a serious and highly prevalent nosocomial disease in which the two large, Rho-glucosylating toxins TcdA and TcdB are the main virulence factors. We report for the first time crystal structures revealing how neutralizing and non-neutralizing single-domain...

Structure and stability of carbohydrate-lipid interactions: Methylmannose polysaccharide-fatty acid complexes
Download2016
Klassen, John S., Siuda, Iwona, Renaud, Justin, Tieleman, D. Peter, Kitova, Elena N., Liu, Lan, Mayer, Paul M., Richards, Michele R., Lowary, Todd L.
We report a detailed study of the structure and stability of carbohydrate–lipid interactions. Complexes of a methylmannose polysaccharide (MMP) derivative and fatty acids (FAs) served as model systems. The dependence of solution affinities and gas-phase dissociation activation energies (Ea) on FA...

Thermal dissociation of streptavidin homotetramer in the gas phase: Subunit loss versus backbone fragmentation
Download2013
Deng, Lu, Klassen, John S., Kitova, Elena N., Sinelnikov, Igor
The results of time-resolved blackbody infrared radiative dissociation experiments performed on gaseous protonated ions, at charge states +15, +16 and +17, of the homotetramer streptavidin (S4) are reported. Evidence is found for three dissociation pathways involving (i) the loss of a single...
