The impulse force model for molecular motors
|
Abstract:
Combining the Brownian ratchet models and the power stroke models, the authors proposed a new mathematical scheme to quantitatively describe the dynamics of molecular motors. That was, a set of functions, periodic either in time or in space, was introduced to modeling the power strokes. Analytic solutions for the probability current are achieved and the relationships of the current with load and asymmetry were seen about. The results were consistent with experimental data. There was no need for the interaction potential between the molecular motor and its track was asymmetric in this model, which makes it more robust than the Brownian ratchet models.
