|Gene:||OsFRO2||Accession Number: G-10685 (MetaCyc)|
Species: Oryza sativa
A cDNA clone encoding a putative ferric chelate reductase OsFRO2 was isolated from Oryza. Northern blot analysis showed that transcripts are expressed only in leaves of Fe-deficient rice plants. The reductase activity is beleived to be impaired based on imperfectly conserved cofactor-binding motifs [Ishimaru06].
Molecular Weight of Polypeptide: 58.4 kD (from nucleotide sequence), 58.4 kD (experimental) [Ishimaru06 ]
Unification Links: Entrez:BAD18963
Relationship Links: Entrez-Nucleotide:PART-OF:AB126085
Enzymatic reaction of: ferric chelate reductase
EC Number: 18.104.22.168
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
The reaction is physiologically favored in the opposite direction.
In Pathways: iron reduction and absorption
