Nicotianamine synthase

In enzymology, a nicotianamine synthase (EC 2.5.1.43) is an enzyme that catalyzes the chemical reaction

3 S-adenosyl-L-methionine ${\displaystyle \rightleftharpoons }$ 3 S-methyl-5'-thioadenosine + nicotianamine

Hence, this enzyme has one substrate, S-adenosyl-L-methionine, and two products, and nicotianamine.

This enzyme belongs to the family of transferases, specifically those transferring aryl or alkyl groups other than methyl groups. The systematic name of this enzyme class is S-adenosyl-L-methionine:S-adenosyl-L-methionine:S-adenosyl-Lmethioni ne 3-amino-3-carboxypropyltransferase.
