Figure 4.
Comparison of residues around heme. A, IsdH-NEAT3. B, IsdA-NEAT (Protein Data Bank code 2ITF). C, IsdC-NEAT (Protein Data Bank code 2O6P). The bound heme molecules are shown as sticks, with pink carbons; the heme irons appear as orange balls. Residues coordinating heme iron and located around the heme are also shown as sticks; their carbons are shown as green.
