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...

Molecular dynamics simulations of viral neuraminidase inhibitors with the human neuraminidase enzymes: Insights into isoenzyme selectivity
Download2018-05-16
Richards, Michele R, Guo, Tianlin, Hunter, Carmanah D, Cairo, Christopher W.
Inhibitors of viral neuraminidase enzymes have been previously developed as therapeutics. Humans can express multiple forms of neuraminidase enzymes (NEU1, NEU2, NEU3, NEU4) that share a similar active site and enzymatic mechanism with their viral counterparts. Using a panel of purified human...

Klassen, John S., Cairo, Christopher W.Xiong, Zi Jian, Li, Jun, Privé, Gilbert G., Leney, Aneika C., Kitova, Elena N., Darestani, Reza Rezaei, Zou, Chunxia, Nikjah, Sanaz
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...

Protecting group-free immobilization of glycans for affinity chromatography using glycosylsulfonohydrazide donors
Download2015-09-16
Heranadez Armada, Daniel, Santos, Jobette T., Richards, Michele R., Cairo, Christopher W.
A variety of applications in glycobiology exploit affinity chromatography through the immobilization of glycans to a solid support. Although several strategies are known, they may provide certain advantages or disadvantages in how the sugar is attached to the affinity matrix. Additionally, the...

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...

Screening oligosaccharide libraries against lectins using the proxy protein electrospray ionization mass spectrometry assay
Download2016
Kitova, Elena N., Klassen, John S., Fan, Xuxin, Privé, Gilbert G., Cairo, Christopher W., Xiong, Zi Jian, Ng, Kenneth K. S., Zou, Chunxia, Eugenio, Luiz, Li, Jun
An electrospray ionization mass spectrometry (ESI-MS) assay for screening carbohydrate libraries against lectins is described. The assay is based on the proxy protein ESI-MS method, which combines direct ESI-MS protein–ligand binding measurements and competitive protein binding, to simultaneously...
