Interpolation between two (identical sequence) crystal structures of the human enzyme ferrochelatase. The main structural differences are centered around a pi-helix that has been proposed to be important for the enzyme to acquire the substrate iron and deliver it to the active site in the non-oxidized ferrous form so that it can be used to produce heme.
