GSH1 — Brassica juncea

Summary

BJUA03G12160S (GSH1) on chromosome A03 of Indian mustard (Brassica juncea) encodes a glutamate-cysteine ligase. The protein carries a glutamine synthetase/guanidino kinase catalytic domain and belongs to the plant-type glutamylcysteine ligase family. Annotated molecular functions include glutamate-cysteine ligase activity and ATP binding. The gene is associated with glutathione anabolism, sulfur metabolism, oxoacid metabolism and homeostasis, and its product localises to the chloroplast. Studies of related genes in other species link the family to the same EC number (6.3.2.2) and to the GCS A and B subunits.
