Phytochelatins: The Principal Heavy-Metal Complexing Peptides of Higher Plants
TL;DR: These peptides appear upon induction of plant cells with heavy metals and represent the principal metal-binding activities in the cells and are proposed as phytochelatin for this new class of natural products.
Journal ArticleDOI
Phytochelatins, the heavy-metal-binding peptides of plants, are synthesized from glutathione by a specific γ-glutamylcysteine dipeptidyl transpeptidase (phytochelatin synthase)
TL;DR: An enzyme has been discovered and characterized from Silene cucubalus cell suspension cultures that catalyzes the transfer of the gamma-glutamylcysteine dipeptide moiety of glutathione to an acceptors molecule or a growing chain of [Glu(-Cys)](n)-Gly oligomers, thus synthesizing phytochelatins, the metal-binding peptides of higher plants and select fungi.
