Hence, this enzyme has one substrate, S-adenosyl-L-methionine, and two products, S-methyl-5'-thioadenosine 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.
