AAT2 — Camelina sativa

Summary

CsAAT2 (CSA20G030300) on Camelina sativa chromosome 20 encodes an aspartate aminotransferase (EC 2.6.1.1) with L-aspartate:2-oxoglutarate transaminase activity, pyridoxal phosphate binding, and additional copper binding and ATP hydrolase activities. The gene is associated with amino acid metabolism, the TCA cycle, 2-oxoglutarate and glutamate metabolism, and anabolism. It has been linked to seed weight, plant height, leaf composition, root development, meristem growth and identity, inflorescence morphology, organ identity, herbicide sensitivity, zinc sensitivity, and disease tolerance. Localisation evidence connects the product to mitochondria, plastids, cytosol, plasmodesmata, plant-type vacuoles and cell walls, and the proteasome. Related genes in other species are linked to aspartate content, cytosolic aspartate aminotransferase activity, vitamin B6 homeostasis, and zinc deficiency tolerance.
