Nicotianamine

Nicotianamine is a metal-chelating molecule ubiquitous in higher plants.[1] It is also used as a precursor for the synthesis of phytosiderophores which play a key role in iron uptake from the soil in graminaceous plants.[2] Biochemically, it is synthesized by the enzyme nicotianamine synthase, which uses three molecules of S-adenosylmethionine.[3]
