CAT3 — Brassica juncea
Summary
BJUA08G13810S (CAT3) on chromosome A08 of Indian mustard (Brassica juncea) encodes a catalase enzyme (EC 1.11.1.6) with catalase activity, heme binding, and metal binding, placing it in the catalase clade 1/3 family. The protein localises to the peroxisomal lumen, cytosol, cytoplasm, nucleus, and plasmalemma. It is associated with hydrogen peroxide catabolism, response to oxidative stress, signal transduction, seed germination, and homeostasis. The gene is linked to cellular responses to sulfate, nitrogen, and phosphate starvation. Related genes in other species connect the family to hybrid incompatibility, though this is not established for B. juncea.
