A directed binding model of motor protein motion on protein filaments

We propose a new mechanism of motor protein motion on protein filaments, treating the heads as extended objects connected by an elastic neck linker region. In our model, ATP hydrolysis provides chemical energy while directed binding is key in force generation coupled with an elastic neck linker regi...

Description
Summary:We propose a new mechanism of motor protein motion on protein filaments, treating the heads as extended objects connected by an elastic neck linker region. In our model, ATP hydrolysis provides chemical energy while directed binding is key in force generation coupled with an elastic neck linker region storing elastic energy. Simulations of the differential equation of motion, based on this model, agree with experiment for both kinesin and its analog, Ncd, and can also be applied to myosin.
