GST1 — Brassica juncea

Summary

BJUA07G17570S (GST1) on chromosome A07 of Indian mustard (Brassica juncea) encodes a glutathione S-transferase with glutathione transferase activity, glutathione binding, maleylacetoacetate isomerase activity, and transglycosidase activity. The protein contains GST_C_Theta, GST_N_Theta, and GSTT1/2/3 domains, along with an Exostosin_GT47 domain. GST1 is associated with detoxification, toxin breakdown, response to herbicide, defense response, metabolic burst, L-phenylalanine breakdown, glutathione metabolism, glycoprotein anabolism, and auxin signaling. It localizes to the cytoplasm, Golgi stack membrane, and macromolecular complexes. Related genes in other species link the family to additional transferase activities, though these associations are not yet established for this specific gene.
