ProteomicsON-TISSUE DIRECT MONITORING OF GLOBAL HYDROGEN/DEUTERIUM EXCHANGE BY MALDI MASS SPECTROMETRY: TDXMS
Hydrogen/deuterium exchange mass spectrometric methods for protein structural analysis are conventionally performed in solution. We present Tissue Deuterium Exchange Mass Spectrometry (TDXMS), a method to directly monitor deuterium uptake on tissue, as a means to better approximate the deuterium exc...

ProteomicsSubzero hydrogen-deuterium exchange CE-MS
We have performed in solution hydrogen exchange (HDX) on peptide standards and bovine hemoglobin with subsequent quenching, pepsin digestion, and cold capillary electrophoretic separation coupled with mass spectrometry (MS) detection for the benchmarking of a lab built HDX-MS platform. Though neutra...

ProteomicsEukaryotic Ribosome GCN2 interaction Hydrogen/Deuterium Exchange Mass Spectrometry
General control nonderepressible 2 (GCN2) phosphorylates eIF2α, regulating translation in response to nutritional stress. Here, we show that mammalian ribosomes are potent GCN2 activators. Hydrogen/deuterium exchange–mass spectrometry (HDX-MS) showed GCN2 interacting with domain II of the uL10 P-sta...

ProteomicsEpitope Mapping of Human Polyclonal Antibodies to the fHbp Antigen of a Neisseria Meningitidis Vaccine by Hydrogen-Deuterium Exchange Mass Spectrometry (HDX-MS)
Antigen-antibody interactions play a key role in the immune response post vaccination and the mechanism of action of antibody-based biopharmaceuticals. 4CMenB is a multicomponent vaccine against Neisseria meningitidis serogroup B in which factor H binding protein (fHbp) is one of the key antigens. I...

ProteomicsHydrogen-deuterium exchange mass spectrometry of wt Mtr4 with various RNA substrates
Mtr4 is a eukaryotic RNA helicase required for RNA decay by the nuclear exosome. Previous studies have shown how RNA enroute to the exosome threads through the highly conserved helicase core of Mtr4. Mtr4 also contains an arch domain, although details of potential interactions between the arch and R...

ProteomicsGroEL interaction and folding of MetF studied by hydrogen/deuterium exchange – mass spectrometry
The cylindrical chaperonin GroEL and its cofactor GroES mediate ATP-dependent protein folding in E. coli by transiently encapsulating non-native substrate in a nano-cage formed by the GroEL ring cavity and the lid-shaped GroES. We analyzed the spontaneous and chaperonin-assisted folding of the essen...

ProteomicsStabilization of diverse amyloidogenic antibody light chains by small molecules revealed by hydrogen-deuterium exchange mass spectrometry
Antibody light chains can aggregate as amyloid fibrils to cause systemic AL amyloidosis. Amyloid deposition requires unfolding of the light chain from its native state, but the mechanistic details of how this occurs are not fully understood. Inhibiting amyloid formation by stabilizing the precursor ...
