ACS2 — Medicago truncatula
Summary
MTR_5G033230 (ACS2, also known as MtGGT1) encodes a pyridoxal phosphate-dependent aminotransferase with glutamate-glyoxylate, alanine-glyoxylate, and nicotianamine aminotransferase activities, as well as 1-aminocyclopropane-1-carboxylate synthase activity. This gene is associated with photorespiration, nitrogen fixation, nitrate assimilation, ethylene anabolism, and amino acid metabolism, including alanine and glycine anabolism and tyrosine breakdown. It is linked to drought tolerance, seed yield, root elongation, flowering time, plant growth, senescence, and disease resistance. The encoded protein localizes to multiple cellular compartments, including the chloroplast stroma, mitochondria, cytosol, nucleus, and amyloplast membrane. Studies of related genes in other species link the family to glutathione catabolism, UV-B stress response, and virus resistance.
