Zinc ions have an insulin-like (insulinomimetic) effect. A particularly sensitive target of zinc ions is protein tyrosine phosphatase 1B (PTP 1B), a key regulator of the phosphorylation state of the insulin receptor. Modulation of insulin signaling by zinc chelating agents and the recognition of temporal and spatial fluctuations of zinc suggest a physiological role of zinc in insulin signal transduction...
In the cellular environment, the sulfur ligands in zinc/thiolate coordination sites of proteins can be oxidized with concomitant mobilization of zinc. The characterization of such “redox zinc switches” requires the determination of three species, i.e., the zinc-containing complex and the zinc-free complex with the thiolate ligands either reduced or oxidized. Differential chemical modification of thiol...
