Force dependence of the Michaelis constant in a two-state ratchet model for molecular motors.

چکیده
We present a quantitative analysis of recent data on the kinetics of ATP hydrolysis, which has presented a puzzle regarding the load dependence of the Michaelis constant. Within the framework of coarse grained two-state ratchet models, our analysis not only explains the puzzling data, but provides a modified Michaelis law, which could be useful as a guide for future experiments.

Collective dynamics of interacting molecular motors.
The collective dynamics of N interacting processive molecular motors are considered theoretically when an external force is applied to the leading motor. We show, using a discrete lattice model, that the force-velocity curves strongly depend on the effective dynamic interactions between motors and differ significantly from those of a simple approach where the motors equally share the force. Mor...
متن کاملA Biologically Inspired Ratchet Model of Two Coupled Brownian Motors
A ratchet model for coupled Brownian motors, inspired by the motion of individual two-headed molecular motors on cytoskeletal filaments, is proposed. Such motors are modeled as two elastically coupled Brownian particles, each of which moves in a flashing ratchet potential. The ratchet potentials felt by the individual particles are anti-correlated, modeling the successive binding and unbinding ...
متن کاملForce { Velocity Relations of a Two { State CrossbridgeModel for Molecular
{ We discuss the force-velocity relations obtained in a two-state crossbridge model for molecular motors. They can be calculated analytically in two limiting cases: for a large number and for one pair of motors. The eeect of the strain-dependent detachment rate on the motor characteristics is studied. It can lead to linear, myosin-like, kinesin-like and anomalous curves. In particular, we speci...
متن کاملProtein motors and Maxwell's demons: does mechanochemical transduction involve a thermal ratchet?
This paper represents a preliminary effort in considering how protein motors could harness thermal fluctuations to generate force and movement. The initial premise for this model is the thermal motor described by Feynman which consists of a ratchet and an interdigitating, spring-loaded pawl. By analogy, one can imagine that biological motors interact weakly with their filament subunit substrate...
متن کاملThe Kinetics of Enzyme Mixtures
Even purified enzyme preparations are often heterogeneous. For example, preparations of aspartate aminotransferase or cytochrome oxidase can consist of several different forms of the enzyme. For this reason we consider how different the kinetics of the reactions catalysed by a mixture of forms of an enzyme must be to provide some indication of the characteristics of the species present. Based...
