Figure 4

The heme site pocket of GLB-1*. Stereo view of the heme, of the proximal His(101)F8, of the distal Gln(69)E7 and of the surrounding residues contacting the heme. The O₂ molecule is shown in ball-and-stick (violet). When appropriate, residue topological positions are indicated. Hydrogen bonds are dashed. Figure drawn with Molscript [66] (For the electron density maps see additional file 2, figure S2).
