Arsenic metabolism by microbes in nature and the impact on arsenic …
2009年12月1日 · Microorganisms have developed various strategies to counter-act arsenic toxicity: firstly, active extrusion of arsenic; secondly, intracellular chelation (in eukaryotes) by various metal-binding peptides including glutathione (GSH), phytochelatins (PCs), and metallothioneins (MTs); thirdly, arsenic transformation to various organic forms which ...
New mechanisms of bacterial arsenic resistance - ScienceDirect
2016年2月1日 · ArsM transforms inorganic arsenic into a highly toxic organoarsenical species that kills off by competing the bacterial species and may also be responsible for carcinogenesis in animals. Competing microbial species have responded to this environmental pressure by evolving detoxification mechanisms for MAs(III).
