PHYTOCHELATIN

Phytochelatin

Poly-glutathione peptides composed of (Glu-Cys)n-Gly where n is two to seven

Phytochelatins are oligomers of glutathione, produced by the enzyme phytochelatin synthase. They are found in plants, fungi, nematodes and all groups

Phytochelatin

Glutathione

Ubiquitous antioxidant compound in living organisms

system that reduces poisonous hydrogen peroxide. It is the precursor of phytochelatins, glutathione oligomers that chelate heavy metals such as cadmium. Glutathione

Carbonic anhydrase

Class of enzymes

transcription and translation of phytochelatin, which are proteins that can bind and transport cadmium. Once bound by phytochelatin, cadmium is no longer toxic

Chelation

Type of chemical bonding with metal ions

histidine, organic diacids such as malate, and polypeptides such as phytochelatin are also typical chelators. In addition to these adventitious chelators
