Kinetic analysis and multiple component monitoring of effectors of adenylyl cyclase activity by quantitative fast-atom bombardment mass spectrometry

Autor: Russell P. Newton, Terence J. Walton, Penny E. Diffley, David E. Games, A.C.R. Wilkins, Mark A. Bayliss, Frank M. Harris, Gareth Brenton, Jan van Geyschem

Publikováno v: Rapid Communications in Mass Spectrometry. 11:1060-1066

The enzyme adenylyl cyclase catalyses the conversion of adenosine 5'-triphosphate (ATP) to adenosine-3',5'-cyclic monophosphate (cyclic AMP), and is an important pharmaceutical target. Quantitation of this enzyme's activity has been carried out by po

Two-electron capture by C3+ ions: competition between single and double electron processes

Autor: A.C.R. Wilkins, A.G. Brenton, A.R. Lee

Publikováno v: International Journal of Mass Spectrometry and Ion Processes. 152:201-208

State-selective translational energy spectroscopy has been used to study two-electron capture processes for 6 keV C3+ ions in collision with He, Ne and Ar atoms. The spectrum for the formation of C+ from the He target reveals only features resulting

Spin violation in double-electron capture by Ar4+ ions

Autor: A.C.R. Wilkins, A.G. Brenton, A.R. Lee, C. Leather

Publikováno v: International Journal of Mass Spectrometry and Ion Processes. 152:21-29

Translational energy spectroscopy has been employed to study state-selective double-electron capture by 8 keV Ar 4+ in He and Ne targets, and 12 keV Ar 4+ in He. The capture spectra are dominated by reaction channels which violate spin conservation.

Collisional Excitation of O+2 and N+2 Electronic States via Single Electron Capture by B2+ Ions

Autor: A.R. Lee, A.C.R. Wilkins, A.G. Brenton, C. Leather

Publikováno v: Journal of Molecular Spectroscopy. 173:603-608

High-resolution translational energy spectra have been obtained for single-electron capture by 4-keV B2+ ions in collision with Ne, O2, and N2. The Ne spectrum is used for accurate determination of the zero energy-change position for subsequent analy
