Protein

Glutathione gamma-glutamylcysteinyltransferase 2

Gene

PCS2

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Involved in the synthesis of phytochelatins (PC) and homophytochelatins (hPC), the heavy-metal-binding peptides of plants.3 Publications
