Cytochrome c多電荷イオンのプロトン移動反応のOPIG-DC電圧依存性
In vivo, it is difficult to examine the structure and function of biomolecules because there are interactions with water molecules in addition to interactions between biomolecules. The purpose of this study was to investigate the properties of biomolecules in the absence of interaction with other molecules by introducing them into a vacuum. In this study, a self-made tandem mass spectrometer consisting of a quadrupole mass spectrometer (QMASS) and a flight mass spectrometer (TOF-MS) using an electrospray ionization source was used. Using the ionic strength value of the obtained mass spectrum, the reaction rate constantk of the proton transfer reaction was determined. Then, the dependence of proton transfer reaction on DC voltage of octapole ion guide (VDC) was examined. As a result of the experiment, it was found that the reaction rate constant k may increase or decrease as the VDC increases.
