Motor Proteins Have Highly Correlated Brownian Engines
نویسندگان
چکیده
Two headed motor proteins, such as kinesin and dynein, hydrolyze environmental ATP in order to propel unidirectionally along cytoskeletal filaments such as microtubules. In the intensely studied case of kinesin, protein heads of approximate dimension 4 × 4 × 7 nm bind primarily on the α tubulin site of asymmetric α–β 8nm-long tubulin dimers that constitute the microtubular protofilaments. Kinesin dimers overcome local binding forces up to approximately

Modelling processive motor proteins: moving on two legs in the microscopic realm
Biological motion is for a large part powered by motor proteins. These are tiny engines (about a millionth of an inch) that convert chemical energy into mechanical force and motion. Processive motor proteins are among the most sophisticated and well studied of the motor proteins. They consist of two identical ‘feet’ that literally step forward on a long polymer as the fuel is consumed. When a h...
متن کاملRealistic Models of Biological Motion
The origin of biological motion can be traced back to the function of molecular motor proteins. Cytoplasmic dynein and kinesin transport organelles within our cells moving along a polymeric filament, the microtubule. The motion of the myosin molecules along the actin filaments is responsible for the contraction of our muscles. Recent experiments have been able to reveal some important features ...
متن کاملEfficiency at maximum power: An analytically solvable model for stochastic heat engines
We study a class of cyclic Brownian heat engines in the framework of finite-time thermodynamics. For infinitely long cycle times, the engine works at the Carnot efficiency limit producing, however, zero power. For the efficiency at maximum power, we find a universal expression, different from the endoreversible Curzon-Ahlborn efficiency. Our results are illustrated with a simple one-dimensional...
متن کاملThe Role of Protein Flexibility in Molecular Motor Function: Coupled Diffusion in a Tilted Periodic Potential
Biomolecular motors are tiny engines that transport material at the microscopic level within biological cells. It has been proposed that many such motors operate, at least in part, by a Brownian ratchet mechanism. Since biomolecular motors typically transport cargo that are much larger than themselves, one would expect the speed of such a motor to be severely limited by the small diffusion coef...
متن کاملBrownian molecular motors driven by rotation-translation coupling.
We investigated three models of Brownian motors which convert rotational diffusion into directed translational motion by switching on and off a potential. In the first model a spatially asymmetric potential generates directed translational motion by rectifying rotational diffusion. It behaves much like a conventional flashing ratchet. The second model utilizes both rotational diffusion and drif...
