Transitions, Transition States, Transition State Analogues: Zinc Pyrazolylborate Chemistry Related to Zinc Enzymes
TL;DR: The Freiburg enzyme model as mentioned in this paper was developed to simulate the protein environment by attachment of the metal to three heterocyclic nitrogen donors of a trispyrazolyl)borate ligand and by encapsulation of zinc by the three substituents R attached at the 3-positions of the pyrazole rings.

Separation of the Phosphoric Esters on the Filter Paper Chromatogram
C. S. Hanes,F. A. Isherwood +1 more
TL;DR: Progress in this important field has depended upon the development of methods for identifying and determining the individual esters present in mixtures, but these methods frequently fail to yield diagnostic results.

Proton Relaxation Times in Paramagnetic Solutions. Effects of Electron Spin Relaxation
N. Bloembergen,L. O. Morgan +1 more
TL;DR: In this article, it was shown that the distortion of the hydrated complex by collisions with other water molecules is responsible for the decrease in T2 in Mn++ (and other) solutions in very high magnetic fields.

Proton Relaxation in Dilute Solutions of Cobalt(II) and Nickel(II) Ions in Methanol and the Rate of Methanol Exchange of the Solvation Sphere
Z. Luz,S. Meiboom +1 more
TL;DR: In this paper, the nuclear relaxation of the hydroxyl and methyl protons in methanol with low concentrations of Co++ and Ni++ ions has been investigated between −80°C and + 80°C.

Ion-exchange chromatography of nucleotides on poly-(ethyleneimine)-cellulose thin layers☆
K. Randerath,E. Randerath +1 more
TL;DR: A great number of naturally occurring mononucleotides can be separated and identified by poly(ethyleneimine)-cellulose thin-layer chromatography by comparison with other present techniques for separating nucleotides.
Journal ArticleDOI
Nuclear magnetic resonance spectra of adenosine di- and triphosphate. II. Effect of complexing with divalent metal ions.
TL;DR: The chemical shifts of the proton magnetic resonance spectra in the nucleotides could be compared with the shifts in the metal complexes to determine the interaction of the metal ion with the adenine ring, thus specifying the nature of the met.al complexes formed.
