MetabolomicsIntegrating two chromatographies in a co-fractionation mass spectrometry approach improved protein-metabolite interactions (PMIs) mapping capabilities and revealed novel protein-ligand pairings in Escherichia coli.
The protein-metabolite interactome remains understudied. We previously developed a co-fractionation mass-spectrometry-based approach called PROMIS to address this gap. PROMIS relies on size separation chromatography of protein-metabolite complexes from lysates, followed by proteomics and metabolomic...

MetabolomicsAntioxidant Activity, Phytochemical Profiling by UPLC-QTOF-MS, and In Silico Targeting of the RNA-Binding Protein DRBD18 of Trypanosoma brucei by Bioactive Compounds from Tetradenia riparia and Tetracera poggei
Oxidative stress plays a key role in the pathogenesis of African trypanosomiasis, and plant-derived antioxidants represent a promising source of dual-action compounds capable of both scavenging reactive oxygen species and interfering with parasite survival. The present study investigates the antioxi...

ProteomicsPhosphorylation of cytosolic hPGK1 affects protein stability and ligand binding: implications for its subcellular targeting in cancer
Human phosphoglycerate kinase 1 is a key glycolytic enzyme that regulates the balance between ADP and ATP concentrations inside the cell. Phosphorylation of hPGK1 at S203 and S256 has been associated with enzyme import from the cytosol to the mitochondria and the nucleus, respectively. These changes...

ProteomicsLigand binding and conformational dynamics of the E. coli nicotinamide nucleotide transhydrogenase revealed by hydrogen/deuterium exchange mass spectrometry
Nicotinamide nucleotide transhydrogenases are integral membrane proteins that utilizes the proton motive force to reduce NADP+ to NADPH while converting NADH to NAD+. Atomic structures of various transhydrogenases in different ligand-bound states have become available, and it is clear that the molec...
