1999 journal article

Conditions of strict voltammetric reversibility of the H+/H-2 couple at platinum electrodes

ANALYTICAL CHEMISTRY, 71(1), 243–246.

TL;DR: Cyclic voltammetric curves obtained at Pt electrodes for the hydrogen couple, H(+)/H(2), fit very well the Shuman theory, as corrected, for reversible electrode processes of other than 1:1 stoichiometry. (via Semantic Scholar)

1999 journal article

Three-dimensional solution structure of mouse [Cd-7]-metallothionein-1 by homonuclear and heteronuclear NMR spectroscopy

PROTEIN SCIENCE, 8(12), 2630–2638.

By: K. Zangger*, G. Oz*, J. Otvos* & I. Armitage n

author keywords: Cd-113; 2D NMR; accordion-HMQC; mouse metallothionein-1; nuclear magnetic resonance; structure
MeSH headings : Amino Acid Sequence; Animals; Cadmium / chemistry; Magnetic Resonance Spectroscopy; Metallothionein / chemistry; Mice; Models, Molecular; Molecular Sequence Data; Protein Isoforms / chemistry; Protein Structure, Tertiary; Rats; Solutions
TL;DR: Structural comparison with rat liver MT2 showed high similarity, with the β‐domain structure in mouse MT1 showing evidence of increased flexibility compared to the same domain in MT2, and the latter was reflected by the presence of fewer interresidue NOEs, no slowly exchanging backbone amide protons, and enhanced cadmium‐cadmium exchange rates found in theβ‐domain of MT1.
