[A possible role of myosin conformers in provision of dual-stage superprecipitation kinetics of natural actomyosin].
It has been shown that synchronous starting and successive accomplishment of superprecipitation on the two types of actomyosin complexes lead to the two-stage kinetics of this reaction. By means of a temperature change different balance of two types of actomyosin macromolecules can be achieved. We conclude that two different structural forms (conformers) of myosin cause two non-equivalent functional states of the whole actomyosin complex.
