Figure 3.
Fig. 3. Ball-and-stick diagrams of three heme-binding
pockets. Structures are shown for Glycera dibranchiata
hemoglobin (PDB ID: 2HBG) (Left), BjFixLH (Center), and the NO
transporter protein (PDB ID: 1NP1) (Right) (27, 28). The
rightmost and leftmost side chains correspond to the E7 and E11
residues of hemoglobins, respectively. The additional side chain
in BjFixLH (red) corresponds to Ile 215. The structures were
aligned based on the orientation of the proximal histidine and
the porphyrin ring. The atoms are colored as in Fig. 1.
