AAT — Daucus carota subsp. sativus

Summary

DCAR_017393 (symbol AAT, also known as DcAAT) on carrot chromosome 5 encodes a pyridoxal phosphate-dependent aminotransferase belonging to the aminotransferase class I/II family, with annotated activities including kynurenine-oxoglutarate transaminase, LL-diaminopimelate aminotransferase, and nicotianamine aminotransferase. The gene is associated with amino acid metabolism, specifically tyrosine breakdown and L-phenylalanine anabolism, as well as ethylene anabolism, systemic acquired resistance via salicylic acid signaling, fruit ripening, somatic embryogenesis, and regeneration. Its product localizes to the cytoplasm and amyloplast membrane. Studies of related genes in other species link the family to chlorophyll content.
