Figure 6

Docking of FMN to heme 2 in the crystal structure of MtrC. (A) Best poses of FMN in clusters 1 (yellow), 4 (green), and 6 (blue) of the histogram shown in Fig. 5 (i.e., the cluster with the strongest binding affinity and the two most populated clusters). Heme 2 is shown (orange) as well as the rectangular Autodock search box (blue). (B) Closeup on the best pose of FMN in cluster 1, indicating individual hydrogen bonds (black) together with the protein residues involved. The closest distance between the planar headgroup of FMN and the porphyrin edge is 3.5 Å. To see this figure in color, go online.
