Fig. 3From: Divergence and adaptive evolution of the gibberellin oxidase genes in plantsActive site core of 2-oxoglutarate-dependent dioxygenases. Amino acid residues that bind the active-site Fe and those that interact with the 5-carboxylate of 2-oxoglutarate are highlighted in green and red, respectively. Six GAox homologs from algae are highlighted in blue Back to article page
