Myosin V molecular motor
4 просмотра
26 фев 2016In living systems, molecules called molecular motors convert chemical energy into mechanical motion, and are essential for many life processes including intracellular transport, cell division, and muscle contraction. Myosin V is a type of molecular motor that transports cargo through cells by "walking" along filaments. In contrast to human-made motors, molecular motors operate in an environment where fluctuations due to Brownian motion are significant. Ongoing experimental and theoretical research is aimed at understanding the mechanism by which molecular motors achieve coordinated, directed motion in a thermal environment.
