113Cd NMR as a probe of the active sites of metalloenzymes
Computer simulation of the EPR spectra of mononuclear and dipolar coupled Cu(II) ions in nitric oxide- and nitrite-treated hemocyanins and tyrosinase
Magnetic dipole-dipole coupled Cu(II) pairs in nitric oxide-treated tyrosinase: a structural relationship between the active sites of tyrosinase and hemocyanin.
The results establish the presence of a pair of copper ions at the active site of tyrosinase, and a clsoe structural relationship between this active site and that of hemocyanin.

The extreme sensitivity of the active site 113Ccd ion's chemical shift to minor changes in the coordination sphere is shown by the isolation of the bovine isozyme A for which the resonance of the 113Cd derivative undergoes an 88-ppm shift on I- binding.

MULTINUCLEAR NMR APPROACHES TO THE SOLUTION STRUCTURE OF ALKALINE PHOSPHATASE: 13C, 19F, 31P, AND 113Cd NMR*
Structure, Mechanism, and Toxicity
An approach beginning with an evaluation of general principles governing simple metal interactions with biological ligands and then applying this information to the evaluation and prediction of metal reactions at higher levels of biological organization was utilized.
NEW APPROACHES TO STUDY EFFECTS OF METALS AND THEIR COMPOUNDS IN VITRO AND IN VIVO
- A. J. Uiterkamp
In vitro and in vivo test systems and some non-invasive instrumental techniques to study effects of metals and their compounds are briefly reviewed. Emphasis is on short-term tests for…
