Force-Velocity Relations of a Two-State Crossbridge Model for Molecular Motors

Soft Condensed Matter 2008-02-03 v2 Statistical Mechanics

Abstract

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 effect 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 specify the conditions under which oscillatory behavior may be found.
