Abstract excerpt
Human cardiac muscle function is regulated by interactions between the thick (myosin) and thin (actin) filaments, driven by conformational changes in myosin coupled to ATP hydrolysis, enabling force generation. During the recovery stroke, myosin undergoes conformational rearrangements that position active site residues for ATP hydrolysis and actin interaction, making it a critical step in the kinetic cycle....
