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...

Sun, Nian, Klassen, John S., Bai, Yu, Liu, Lan, Xia, Li, Lowary, Todd L.
The interactions between 3-O-methyl-mannose polysaccharides (MMPs), extracted from Mycobacterium smegmatis (consisting of a mixture of MMP-10, -11, -12 and -13) or obtained by chemical synthesis (MMP-5s, -8s, -11s and -14s), and linear saturated and unsaturated fatty acids (FAs), and a commercial...

Quantifying labile protein-ligand interactions using electrospray ionization mass spectrometry
Download2010
El-Hawiet, Amr, Klassen, John S., Kitova, Elena N., Liu, Lan
A new electrospray ionization mass spectrometry (ES-MS) approach for quantifying protein—ligand complexes that are prone to in-source (gas-phase) dissociation is described. The method, referred to here as the reference ligand ES-MS method, is based on the direct ES-MS assay and competitive ligand...

El-Hawiet, Amr, N. Kitova, Elena N., Klassen, John S.
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...

Reliable determinations of protein-ligand interactions by direct ESI-MS measurements: Are we there yet?

El-Hawiet, Amr, Klassen, John S., Kitova, Elena N., Schnier, Paul D.
The association-dissociation of noncovalent interactions between protein and ligands, such as other proteins, carbohydrates, lipids, DNA, or small molecules, are critical events in many biological processes. The discovery and characterization of these interactions is essential to a complete...
