(see Figure 3.12).3.2.8 The GFCP and Rotary Enzyme Catalysis
The first direct evidence for the conformational waves (also called
mobile conformational wave packets or conformons) accompanying
enzyme catalysis appears to have been observed by Uchihashi et al. in
2011 (see [85, Figure 3.12(g)]). Using high-speed atomic force micros-
copy (HS-AFM), these investigators observed that ATP hydrolysis
caused a propagation of the conformational changes in the a 3 b 3 sub-
complex of the F 0 F 1 –ATPase, as can be seen in Figure 3.12(g). The
linear speed of the propagation of the conformational waves around the
periphery of the circular complex was found to be about 10 nm/s or
100 Å/s.
The circular propagation of conformational waves measured by
Uchihashi et al. [85] as shown in Figure 3.12(g) serves as the first clear
example of the rotary catalysis as well. The propagation speed of the
conformational waves around the b-subunits in the isolated a 3 b 3 stator
ring (see [85 Figures 1 and 2]) is about 200°/s. The authors concluded that
the “structural basis of the unidirectionality” of the rotary conformational
waves “is programmed in the stator ring” but they did not provide any
molecular mechanisms for the unidirectional wave propagation. One suchFigure 3.11 The SPSP: The interaction between the system and the environment deter-
