The Metallothionein/Thionein System: An Oxidoreductive Metabolic Zinc Link
18 Dec 2008
Abstract excerpt
Metallothioneins (MTs) were discovered more than 50 years ago and identified as low-molecular weight, sulfhydryl-rich proteins that were subsequently found to bind zinc predominantly. The binding of seemingly redox inactive zinc ions allows MT to play a central role in oxidoreductive cellular metabolism, cellular zinc distribution and homeostasis. In this interpretive study, we discuss the interaction of MT with...
