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 anti-cancer drugs against tubulin using catch-and-release electrospray ionization mass spectrometry
Download2016
Kitova, Elena N., Klassen, John S., Winter, Philip, Tuszynski, Jack A., Darestani, Reza R.
Tubulin, which is the building block of microtubules, plays an important role in cell division. This critical role makes tubulin an attractive target for the development of chemotherapeutic drugs to treat cancer. Currently, there is no general binding assay for tubulin–drug interactions. The...

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...

El-Hawiet, Amr, Klassen, John S., N. Kitova, Elena N.
The affinities of the most abundant oligosaccharides found in human milk for four bacterial exotoxins (from Vibrio cholerae and pathogenic Escherichia coli) were quantified for the first time. Association constants (Ka) for a library of 20 human milk oligosaccharides (HMOs) binding to Shiga toxin...

Protein-glycolipid interactions studied in vitro using ESI-MS and nanodiscs: Insights into the mechanisms and energetics of binding
Download2015
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...

Quantifying protein-carbohydrate interactions using liquid sample desorption electrospray ionization mass spectrometry
Download2015
N. Kitova, Elena N., Shams-Ud-Doha, Km, Yao, Yuyu, Klassen, John S., Daneshfar, Rambod
The application of liquid sample desorption electrospray ionization mass spectrometry (liquid sample DESI-MS) for quantifying protein–carbohydrate interactions in vitro is described. Association constants for the interactions between lysozyme and β-D-GlcNAc-(1 → 4)-β-D-GlcNAc-(1 → 4)-D-GlcNAc and...

Protein interactions with glycolipids are implicated in diverse cellular processes. However, the study of protein–glycolipid complexes remains a significant experimental challenge. Here, we describe a powerful new assay that combines electrospray ionization mass spectrometry (ESI-MS) and...
