Figure 9. Interactions of R11, F62, D84 and R176.

Figure 9

A. A closer view of the stacking interaction of R11 with F62 present at the base of the active site loop measured by the distance between the CZ atom of R11 and center of mass of the phenyl ring of F62 in the DPM stage. B. In the P4M stage D84 interacts with R11, disrupting the stacking of R11 with F62. C. Stacking interaction of R11 with F62 keeps the active site loop in a position facilitating its movement during DPM and P3M stages, shown as a distance graph between the CZ atom of R11 and the center of mass of the phenyl ring of F62 in DPM, P3M and P4M stages. D. Distance graph depicting the interaction of R11 with D84 in the P4M stage which causes the stacking between R11 and F62 to break. E. Distance graphs depicting the interaction of R176 with the B (in black) and C (in red) rings of the polypyrrole chain during the stages of chain elongation.
