Rotors elastically deformable

Curve 1 in Fig. 1 under low rotor r.p.m. corresponds to the case when the rate of the stress buildup under the effect of deformation is commensurate with the rate of their relaxation. The development of time-delayed elastic deformations determines the final rate of attainment of the steady-state regime of viscous flow, under which the stationary value of the shear stress is recorded. Starting with the moment of time t, the stress will increase and the period of the viscous-plastic state comes to an end. 

Thus the fundamental predictions of the hydrophobic elastic consilient mechanism are that the rotor would exhibit asymmetric hydrophobicity, that different arrangements of nucleotide analogues representing different states of polarity at the catalytic sites would orient the rotor, and that hydrolysis of ATP in formation of the most polar state at a catalytic site of the involved protein subunit(s) would demonstrate a near-ideal elastic deformation of the y-rotor and the protein subunit(s). Of course, such a mechanism would exhibit high efficiency and reversibility. 

Prediction of Hydrophobically Asymmetric and Elastically Deformable Rotor and Housing... 

AGap available to the Fi-motor, that is, a near maximal apolar-polar repulsive free energy of hydration between the hydrophobic side of the y-rotor and the very polar state, ADP -i- SO , of a catalytic P-subunit. This near-maximal repulsion provides an elastic deformation of rotor and housing as required for efficient function of the ATPase in its performance of chemo-mechanical transduction. 

Accordingly, on hydrolysis to form ADP plus HPOj" the sudden burst of repulsion due to HPO would result in an elastic deformation of the y-rotor and of the associated (3-subimit that would limit torsion angles in a storage of energy that would be nearly fully recovered on the relaxation of rotational motion.
