Although sumoylation regulates a diverse and growing number of recognized biological processes, the molecular mechanisms by which the covalent attachment of the ubiquitin-like protein SUMO can alter the properties of a target protein remain to be established. To address this question, we have...

Identifying nonspecific ligand binding in electrospray ionization mass spectrometry using the reporter molecule method
2009
Kitova, Elena N., Klassen, John S., Sun, Nian, Sun, Jiangxiao
The application of the reporter molecule (Mrep) method for identifying nonspecific complexes in the ES-MS analysis of protein-ligand and DNA-ligand interactions in vitro is described. To test the reliability of the method, it was applied to the ES-MS analysis of protein-carbohydrate complexes...

Nonspecific interactions between proteins and charged biomolecules in electrospray ionization mass spectrometry
Download2010
Kitova, Elena N., Sun, Nian, Klassen, John S., Soya, Naoto
An investigation of the nonspecific association of small charged biomolecules and proteins in electrospray ionization mass spectrometry (ES-MS) is described. Aqueous solutions containing pairs of proteins and a small acidic or basic biomolecule that does not interact specifically with either of...

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...

Sialic acid terminates glycans of glycoproteins and glycolipids that play numerous biological roles in health and disease. Although genetic tools are available for interrogating the effects of decreased or abolished sialoside expression in mice, pharmacological inhibition of the sialyltransferase...

Protein-glycolipid interactions studied in vitro using ESI-MS and nanodiscs: Insights into the mechanisms and energetics of binding
Download2015
Nikjah, Sanaz, Boraston, Alisdair B., Lin, Hong, Kitova, Elena N., Li, Jun, Pluvinage, Benjamin, Han, Ling Han, Klassen, John S.
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...
