Myosin overview

S ATP -I- synthetic peptides <1, 2> (<2> variations in length, and number, location and kind of basic residues of the basic sequence of peptide GRGRSSVYS, overview [7] <1> peptide MH-3, corresponding to myosin II heavy chain from residues 2020 to 2035 except that Ser-2026 and Thr-2031 have been replaced by alanine [2]) (Reversibility <1,2> [2,4,5,7]) [2, 5, 7]... 

Provide an overview of a model for the mechanism of the power stroke during muscle contraction. Explain the roles of actin and the ATPase activity of myosin in the model.
