title: Actomyosin systems of biological motility.
abstract: Evolution of notions on the molecular mechanism of muscle contraction and other events based on the actin-myosin interaction, from the middle of XX century to the present time, is briefly reviewed, including recent views on the functioning of the myosin head as a "molecular motor". The results of structural and functional studies on the myosin head performed by the author and his colleagues using differential scanning calorimetry are also reviewed.
