General Information

General Information Comment Organism
additional information homology modeling using Oryzsa sative isozymes as template Zea mays
physiological function nicotianamine is an important divalent metal chelator and the main precursor of phytosiderophores. nicotianamine is synthesized from S-adenosylmethionine in a process catalyzed by nicotianamine synthase, NAS. Expression of ZmNAS genes is tissue-specific and developmentally regulated Zea mays
