SAT — Brassica juncea

Summary

BJUB04G42500S (SAT) in Indian mustard (Brassica juncea) on chromosome B04 encodes a protein with a CAT-like domain superfamily and exhibits vinorine synthase, acetylase and acyltransferase activities. The gene is associated with indole alkaloid anabolism, alkaloid anabolism, alkaloid metabolism, glutathione metabolism and the electron transport chain. It has been linked to several agronomically relevant traits including sulfur content, photosynthetic ability, transpiration rate, stomatal resistance, chlorophyll content, photochemical quenching and ethylene sensitivity. The encoded protein is localized to both the cytoplasm and nucleus. Studies of related genes in other species link the family to additional acyltransferase activities (EC 2.3.1.160, 2.3.1.322-325, 2.3.1.334) and methyltransferase activity (EC 2.1.1.-).
