The structure of the eight OsaGAoxs. The characteristic conserved domain of each gene is highlighted in purple, amino acid residues that in the characteristic conserved domains identified by two and three programs are highlighted in blue and red, respectively. Residues in that bind the active-site Fe (yellow ball) and those that interact with the 5-carboxylate of 2-oxoglutarate are highlighted in yellow
