生物活性

Phytochelatin 2, a short phytochelatin, is a key plant peptide binding heavy metals. Phytochelatins are a diverse set of plant compounds that chelate metals, protect against metal toxicity and function in metal homeostasis[1][2].

体外研究
(In Vitro)

Phytochelatin synthase (PCS) uses the substrates glutathione (GSH, γGlu-Cys-Gly) and a cadmium (Cd)-bound GSH (Cd∙GS2) to produce the shortest phytochelatin product (PC2, (γGlu-Cys)2-Gly) through a ping-pong mechanism[3].
Phytochelatins and their glutathione (GSH) precursor are thiol-rich peptides that play an important role in heavy metal detoxification in plants and microorganisms[4].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
