Abstract
Native temperature-dependent transitions of subfragment 1 (S1) of skeletal muscle myosin, the process of its melting and some features of its proteolytic degradation have been studied. Sl heavy chain is shown to consist of not less than three structural units. As based on data available in literature and the authors' own results a model of SI three-dimensional organization is suggested.
