Polymer-Based Nanodiscs for Structural and Functional Analyses of Bacterial and Mammalian Membrane Proteins
DownloadSpring 2020
Unlike cytosolic proteins, membrane proteins (MPs) are embedded within the plasma membrane and the lipid bilayer of intracellular organelles. MPs serve in various cellular processes such as ion and metabolite transports, bioenergetic processes, signal transductions, and cell-cell communications....

Quantifying protein-fatty acid interactions using electrospray ionization mass spectrometry
Download2011
Liu, Lan, Kitova, Elena N., Klassen, John S.
The application of the direct electrospray ionization mass spectrometry (ESI-MS) assay to quantify interactions between bovine β-lactoglobulin (Lg) and a series of fatty acids (FA), CH3(CH2)xCOOH, where x = 6 (caprylic acid, CpA), 8 (capric acid, CA), 10 (lauric acid, LA), 12 (myristic acid, MA),...

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?
Download2012
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...

Protein prenylation is the post-translational addition of isoprenoid lipid moieties to proteins, which regulates their subcellular localization and function. Farnesyl or geranylgeranyl isoprenoids are covalently linked to cysteines residues in a C-terminal prenylation recognition sequence in...

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...
