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...

Richards, Michele R., Campuzano, Iain D. G., Kitova, Elena N., Klassen, John S., Li, Jun, Privé, Gilbert G., Xiong, Zi Jian, Bagal, Dhanashri
Saposin A (SapA) lipoprotein discs, also known as picodiscs (PDs), represent an attractive method to solubilize glycolipids for protein interaction studies in aqueous solution. Recent electrospray ionization mass spectrometry (ESI-MS) data suggest that the size and composition of...

Widespread tetracycline resistance (TcR) has limited the clinical use of Tc for the treatment of bacterial infections. Tet(O) protein is present in many bacteria and is the major transmissible TcR determinant in Campylobacter jejuni, a common cause of acute bacterial diarrhea worldwide. Tet(O)...

Localizing carbohydrate binding sites in proteins using hydrogen/deuterium exchange mass spectrometry
Download2016
Kitova, Elena N., Klassen, John S., Eugenio, Luiz, Li, Jun, Ng, Kenneth, Zhang, Jingjing
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...

Han, Ling Han, Kitova, Elena N., Klassen, John S., Pluvinage, Benjamin, Lin, Hong, Nikjah, Sanaz, Li, Jun, Boraston, Alisdair B.
Electrospray ionization-mass spectrometry (ESI-MS) analysis combined with the use of nanodiscs (NDs) to solubilize glycolipids (GLs) has recently emerged as a promising analytical method for detecting protein–GL interactions in vitro and, when applied to libraries of GLs, ranking their...
