Dingle, Tanis C., Szpacenko, Adam, Ng, Kenneth K.S., Kitov, Pavel, Klassen, John S., El-Hawiet, Amr, Kitova,Elena N., Mulvey, George L., Eugenio, Luiz, Armstrong, Glen D.
The binding of recombinant fragments of the C-terminal cell-binding domains of the two large exotoxins, toxin A (TcdA) and toxin B (TcdB), expressed by Clostridium difficile and a library consisting of the most abundant neutral and acidic human milk oligosaccharides (HMOs) was examined...

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...

Heranadez Armada, Daniel, Santos, Jobette T., Richards, Michele R., Cairo, Christopher W.
A variety of applications in glycobiology exploit affinity chromatography through the immobilization of glycans to a solid support. Although several strategies are known, they may provide certain advantages or disadvantages in how the sugar is attached to the affinity matrix. Additionally, the...

Localizing carbohydrate binding sites in proteins using hydrogen/deuterium exchange mass spectrometry
Download2016
Klassen, John S., Kitova, Elena N., Li, Jun, Zhang, Jingjing, Ng, Kenneth, Eugenio, Luiz
The application of hydrogen/deuterium exchange mass spectrometry (HDX-MS) to localize ligand binding sites in carbohydrate-binding proteins is described. Proteins from three bacterial toxins, the B subunit homopentamers of Cholera toxin and Shiga toxin type 1 and a fragment of Clostridium...

Screening oligosaccharide libraries against lectins using the proxy protein electrospray ionization mass spectrometry assay
Download2016
Privé, Gilbert G., Ng, Kenneth K. S., Xiong, Zi Jian, Klassen, John S., Kitova, Elena N., Fan, Xuxin, Li, Jun, Zou, Chunxia, Eugenio, Luiz, Cairo, Christopher W.
An electrospray ionization mass spectrometry (ESI-MS) assay for screening carbohydrate libraries against lectins is described. The assay is based on the proxy protein ESI-MS method, which combines direct ESI-MS protein–ligand binding measurements and competitive protein binding, to simultaneously...

Jia, Feng, Howlader, Md. Amran, Cairo, Christopher W.
Integrins are critical receptors in cell migration and adhesion. A number of mechanisms are known to regulate the function of integrins, including phosphorylation, conformational change, and cytoskeletal anchoring. We investigated whether native neuraminidase (Neu, or sialidase) enzymes which...
