Hydrogen-deuterium exchange mass spectrometry
WebHydrogen/deuterium exchange (HDX) monitored by mass spectrometry (HDX-MS) has become a valuable tool in studies of protein dynamics and protein interactions. Isotopic exchange is typically initiated by diluting a protein solution into deuterated buffer at physiological conditions. WebHere, we corroborated those findings with kinetic studies, employing hydrogen-deuterium exchange mass spectrometry (HDX-MS). Many overlapping apoA-I digested peptides exhibited bimodal HDX kinetics behavior, suggesting that apoA-I regions with the same amino acid composition located on different apoA-I chains had different conformations …

Hydrogen–deuterium exchange (also called H–D or H/D exchange) is a chemical reaction in which a covalently bonded hydrogen atom is replaced by a deuterium atom, or vice versa. It can be applied most easily to exchangeable protons and deuterons, where such a transformation occurs in the … Meer weergeven In protic solution exchangeable protons such as those in hydroxyl or amine group exchange protons with the solvent. If D2O is solvent, deuterons will be incorporated at these positions. The exchange reaction can be … Meer weergeven H–D exchange was measured originally by the father of hydrogen exchange Kaj Ulrik Linderstrøm-Lang using density gradient tubes. In modern times, H–D exchange has primarily been monitored by the methods: NMR spectroscopy, mass spectrometry Meer weergeven Neutron scattering Perdeuteration of one component of a multi-component system can provide contrast for neutron scattering experiments, where the … Meer weergeven • David Weis, Ed.
