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.

体外研究:
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. Phytochelatins and their glutathione (GSH) precursor are thiol-rich peptides that play an important role in heavy metal detoxification in plants and microorganisms.
