Fig. 15: Overall view of the crystal structure of the N2OR dimer; one monomer is uniformly coloured grey while the other monomer is colour coded as a function of secondary structure. The labels of the coloured monomer (N- and C- termini, the copper centres, Cl­ ion, blade and insertion numbering) are in red; labels for the second monomer are in blue. Blades are numbered from 1 to 7. Seven insertions are identified: labelled I to VII.
