Nicotianamine synthase explained

nicotianamine synthase
Ec Number:	2.5.1.43
Cas Number:	161515-44-2
Go Code:	0030410

In enzymology, a nicotianamine synthase is an enzyme that catalyzes the chemical reaction

3 S-adenosyl-L-methionine

\rightleftharpoons 3 S-methyl-5'-thioadenosine + nicotianamine

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.
