DE   nicotianamine aminotransferase.
AN   NAAT.
AN   NAAT-I.
AN   NAAT-II.
AN   NAAT-III.
AN   nicotianamine transaminase.
CA   2-oxoglutarate + nicotianamine = 3''-deamino-3''-oxonicotianamine +
CA   L-glutamate.
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.
