Structure comparison among the porcine b5 structures. (a) Superposition of C^α atoms between the form 1 (blue) and form 2 (pink) structures of the oxidized forms. (b) Superposition of C^α atoms between the form 1 (orange) and form 2 (green) structures of the reduced forms. (c) Superposition of C^α atoms between the oxidized (blue) and reduced (orange) forms of the form 1 structures. (d) Superposition of C^α atoms between the oxidized (pink) and reduced (green) forms of the form 2 structures. (e) Superposition of the atoms in the porphyrin rings between the form 1 (blue) and form 2 (pink) structures of the oxidized forms. (f) Superposition of the atoms in the porphyrin rings between the form 1 (orange) and form 2 (green) structures of the reduced forms.
