Figure 3
Superposition of C2-Cgb and the Ngb–CO complex (PDB code 1w92 ) showing the haem environment in stereo. The stick models of C2-Cgb and the Ngb–CO complex are coloured yellow and pink, respectively. The labels on the residues of C2-Cgb and Ngb complex are coloured black and red, respectively. The label in parentheses represents the helix name and the position in the helix. Arg84(E10) of Cgb interacts with Glu94′(E20) of the dimer partner. The structural change of Ngb on CO binding involves rotation of the side chain of Phe106(G5) and a slide of the haem. In the case of Cgb, however, steric collisions between Phe124(G5) and Val162(H19) do not allow such movements. |
