Fig. 4. Structural details of the heme pocket in E. coli
ferric unliganded flavohemoglobin. The heme molecule is shown in
stereo together with a selection of amino acid residues within
the pocket at 5 Å from the macrocycle. The phenolic ring
of Tyr29-B10 located at >5 Å from the heme is also shown,
whereas the Phe^43-CD1 is hidden for clarity. The picture was
obtained with the program MOLSCRIPT (28).
