AAT — Solanum tuberosum

Summary

PGSC0003DMG400027919, also known as AAT or PAT, encodes a pyridoxal phosphate-dependent aminotransferase with multiple annotated activities including L-glutamate:prephenate, L-aspartate:prephenate, nicotianamine, and L-tyrosine-2-oxoglutarate transaminase activities, as well as 1-aminocyclopropane-1-carboxylate synthase activity. The gene is associated with tyrosine breakdown, carotenoid and phenylalanine anabolism, ethylene biosynthesis, amino acid metabolism, systemic acquired resistance via salicylic acid signaling, shoot regeneration, and fruit, seed, and embryo development. It is linked to carotenoid content and parthenocarpic fruit development. The protein localizes to the amyloplast membrane and chloroplast stroma. Related genes in other species are linked to aromatic amino acid biosynthesis and protein stability.
