Rates from the coalescence of relaxation times
Autor: Joseph B. Lambert, Joe W. Keepers
Publikováno v: Journal of Magnetic Resonance (1969). 38:233-244
A method has been developed for obtaining intramolecular exchange rates in liquids from the coalescence of nonselective 13 C spin-lattice relaxation times for the general case in which T 1 at the two sites can have any relative values. Regression ana

A theoretical study of distance determinations from NMR. Two-dimensional nuclear overhauser effect spectra
Autor: Thomas L. James, Joe W. Keepers
Publikováno v: Journal of Magnetic Resonance (1969). 57:404-426
In principle, two-dimensional nuclear Overhauser effect NMR experiments can be used to establish internuclear distances and thus to determine molecular structure in solution. Theoretical calculations have been carried out for the 2D NOE experiment ad

Investigation of the solution structure of a DNA octamer [d(GGAATTCC)]2 using two-dimensional nuclear Overhauser enhancement spectroscopy
Autor: Michelle S. Broido, Joe W. Keepers, Thomas L. James, Gerald Zon
Publikováno v: European Journal of Biochemistry. 150:117-128
Proton two-dimensional nuclear Overhauser enhancement (2D NOE) spectra in the pure absorption phase were obtained at 500 MHz for [d(GGAATTCC)]2 in aqueous solution at a series of mixing times. The experimental data were analyzed by comparison with th

Publikováno v: Biopolymers. 23:2901-2929
Molecular-mechanical simulations have been carried out on “mismatched base” analogs of the DNA double-helical structure d(CGCGAATTCGCG)2, in which the base pairs CG at the 3 and 10 positions have been replaced by CA, AG, TC, and TG base pairs, as

Molecular mechanical studies of DNA flexibility: Coupled backbone torsion angles and base-pair openings
Autor: Peter A. Kollman, Paul K. Weiner, Thomas L. James, Joe W. Keepers
Publikováno v: Proceedings of the National Academy of Sciences. 79:5537-5541
Molecular mechanics studies have been carried out on “B-DNA-like” structures of [d(C-G-C-G-A-A-T-T-C-G-C-G)] 2 and [d(A)] 12 ·[d(T)] 12 . Each of the backbone torsion angles (ψ, φ, ω, ω′, φ′) has been “forced” to alternative values

The Kinetics of Intramolecular Reactions from Relaxation Time Measurements
Autor: Joe W. Keepers, Ronald J. Nienhuis, Joseph B. Lambert
Publikováno v: Angewandte Chemie International Edition in English. 20:487-500
Analysis of spin-lattice relaxation (T1) provides alternatives to the standard line shape procedures for the investigation of intramolecular reactions; furthermore it expands the NMR range at both the high and the low energy barrier limits. Dipole-di

Die Bestimmung der Spin-Gitter-Relaxationszeit (T1) bietet eine Alternative zu den ublichen NMR-Linienformanalysen, um die Kinetik intramolekularer Reaktionen zu untersuchen; obendrein kann der durch NMR-Spektroskopie erfasbare Bereich sowohl nach ho
