ENZYME entry: EC 2.6.1.80

Accepted Name
Nicotianamine aminotransferase.
Alternative Name(s)
NAAT.
NAAT-I.
NAAT-II.
NAAT-III.
Nicotianamine transaminase.
Reaction catalysed
Nicotianamine + 2-oxoglutarate <=> 3''-deamino-3''-oxonicotianamine + L-glutamate
Cofactor(s)
Pyridoxal 5'-phosphate.
Comment(s)
This enzyme is produced by grasses. They secrete both the nicotianamine and the transaminated product into the soil around them. Both compounds chelate Fe(2+) and Fe(3+); these chelators, called mugineic acid family phytosiderophores, are taken up by the grass, which is thereby supplied with iron.
