Structure of N-terminal cupredoxin domain of N. yellowstonii amoB subunit (Ny_amoB). Center: Overall structure (pink with copper ions as gray spheres) with analogous domain of M. capsulatus (Bath) pmoB (magenta with copper ions as dark blue spheres) superimposed. Upper-left: Zoomed-in view of insertion region with residues 55–88 shown in gray and residues at interface with core domain shown as sticks. Upper-right: Zoomed-in view of copper binding sites in M. capsulatus (Bath) pmoB and Ny_amoB.
