Metabolic networks are interconnected and influence diverse cellular processes. The protein-metabolite interactions that mediate these networks are frequently low affinity and challenging to systematically discover. We developed mass spectrometry integrated with equilibrium dialysis for the disco...
Large-scale identification of N-linked intact glycopeptides by liquid chromatography coupled tandem mass spectrometry (LC-MS/MS) in human serum is challenging due to the wide dynamic range of serum protein abundances, the lack of a complete serum N-Glycan database and the existence of non-specifical...

INTRODUCTION: Interesting data about the family Asteraceae as a new source of Leishmania major dihydroorotate dehydrogenase (LmDHODH) inhibitors are presented. This key macromolecular target for parasites causing neglected diseases catalyzes the fourth reaction of the de novo pyr...
Although thousands of intact proteins can be feasibly identified in recent years, global quantification of intact proteins is still challenging. Herein, we develop a high-throughput strategy for global intact protein quantification based on chemical isotope labeling. The isotope incorporation effici...
Optimization of intact protein TMT labeling and multidimensional high-pH/low-pH RP/RPLC-MS/MS. Application of this platform for quantification of proteoform-level abundance changes as a result of staursporine treatment in HeLa cells.
A comprehensive characterization of biotherapeutics, mandated by regulatory authorities, require analyses of a protein drug at multiple structure levels. Such multi-level characterization can be performed by mass spectrometry (MS), with established conventional MS-based assays of product quality att...
This ProteomeXchange dataset contains native mass spectrometry and intact-protein mass spectrometry data generated in support of the manuscript “A labile sulfur ligand in a three-cysteine-coordinated [2Fe-2S] cluster mediates sulfide sensing in NreB”. The dataset includes intact-protein MS measureme...

To open new ways for MALDI-MS-based patient screening, blood serum is the most preferred specimen because of its richness in patho-physiological information and due to ease of collection. To overcome deleterious freeze / thaw cycles and to reduce high costs for shipping and storage, we sought to dev...
