The AcFeSOD protein was expressed in a stable form using an Escherichia coli expression system and was crystallized by the microbatch and hanging-drop vapour-diffusion methods. The structure was determined to 2.33 A resolution from a single AcFeSOD crystal. The crystal belonged to the hexagonal space group P61 and contained 12 molecules forming three tetramers in the asymmetric unit, with an iron ion bound in each molecule. Structural comparisons and sequence alignment of AcFeSOD with other FeSODs showed a well conserved overall fold and conserved active-site residues with subtle differences.
