Nicotianamine aminotransferase explained
| Nicotianamine aminotransferase |
| Ec Number: | 2.6.1.80 |
In enzymology, a nicotianamine aminotransferase is an enzyme that catalyzes the chemical reaction
nicotianamine + 2-oxoglutarate
3"-deamino-3"-oxonicotianamine + L-glutamate
Thus, the two substrates of this enzyme are nicotianamine and 2-oxoglutarate, whereas its two products are 3-deamino-3-oxonicotianamine and L-glutamate.
This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is nicotianamine:2-oxoglutarate aminotransferase; nicotianamine transaminase. Other names in common use include NAAT, NAAT-I, NAAT-II, and NAAT-III.
