MetaCyc Enzyme: nicotianamine synthase

Gene: OsNAS3 Accession Number: G-10641 (MetaCyc)

Synonyms: nicotianamine synthase 3

Species: Oryza

Summary:
A cDNA clone was isolated from rice seedling. The cDNA was recombinantly expressed in transgenic rice plants. The protein was shown to be a nicotianamine synthase and catalyzes the trimerization of SAM into nicotamine [Higuchi01].

Molecular Weight of Polypeptide: 36.9 kD (from nucleotide sequence), 36.9 kD (experimental) [Higuchi01 ]
