GST — Cicer arietinum

Summary

LOC101508557 (CaGST) on chickpea chromosome 4 encodes a glutathione S-transferase (GST) belonging to the Phi class, as indicated by its GST_Phi_C and GST_C domains. The enzyme possesses glutathione transferase activity, glutathione binding, and protein homodimerization activity, and is associated with glutathione metabolism, detoxification, and toxin breakdown. CaGST is associated with responses to xenobiotic stimuli, herbicides, hydrogen peroxide, and salicylate, as well as auxin signaling and seed development. It is localized to the cytoplasm and macromolecular complexes. CaGST is associated with seed size. Studies of related genes in other species link the family to glutathione transferase activity (EC 2.5.1.18), though these specific associations are not yet established in chickpea.
