Metal ions affect insulin-degrading enzyme activity.

Insulin degradation is a finely tuned process that plays a major role in controlling insulin action and most evidence supports IDE (insulin-degrading enzyme) as the primary degradative agent. However, the biomolecular mechanisms involved in the interaction between IDE and its substrates are often obscure, rendering the specific enzyme activity quite difficult to target. On the other hand, biome...

Proteomics of heavy metal toxicity in plants.

Plants endure a variety of abiotic and biotic stresses, all of which cause major limitations to production. Among abiotic stressors, heavy metal contamination represents a global environmental problem endangering humans, animals, and plants. Exposure to heavy metals has been documented to induce changes in the expression of plant proteins. Proteins are macromolecules directly responsible for mo...

Neutralization by Metal Ions of the Toxicity of Sodium Selenide

Inert metal-selenide colloids are found in animals. They are believed to afford cross-protection against the toxicities of both metals and selenocompounds. Here, the toxicities of metal salt and sodium selenide mixtures were systematically studied using the death rate of Saccharomyces cerevisiae cells as an indicator. In parallel, the abilities of these mixtures to produce colloids were assesse...
