a Comparative model of ferredoxin NADP+ reductase from Gracilaria chilensis. Secondary structures are shown by arrows (β strands) and cylinders (α helices); FAD is shown as orange sticks and NADP as purple sticks. b Close up of the residues involved in the NADP+ binding site, c close up of the residues involved in the FAD binding site. d Docking model of FNR (grey surface), showing the two co-substrates, NADP+ and ferredoxin, the co-factor FAD and the 2[FeS] cluster. e Close-up of the complex showing residues of the interface included in the text
