ID 2.6.1.80 DE Nicotianamine aminotransferase. AN NAAT. AN NAAT-I. AN NAAT-II. AN NAAT-III. AN Nicotianamine transaminase. CA Nicotianamine + 2-oxoglutarate = 3''-deamino-3''-oxonicotianamine + CA L-glutamate. CF Pyridoxal 5'-phosphate. CC -!- This enzyme is produced by grasses. CC -!- They secrete both the nicotianamine and the transaminated product CC into the soil around them. CC -!- Both compounds chelate Fe(2+) and Fe(3+); these chelators, called CC mugineic acid family phytosiderophores, are taken up by the grass, CC which is thereby supplied with iron.
