[A cross-bridge model for the artificial mobile systems].

A simple kinetic scheme of the mechano-chemical cycle of the cross-bridge is proposed. It was found on the experiments with using of caged ATP and the experiments with the limited number of the myosin molecules in motility assay in vitro. The model reproduces the results of the experiments in motility assay in vitro and allows to investigate the actin-myosin complexes at an external load condition.
