Actin myosin cell movement.doc; Page 5 of 16 6. This translation of chemical energy to movement is mediated by changes in the shape of myosin resulting from ATP binding. The generally accepted model (the swinging-cross-bridge model) is that ATP hydrolysis drives repeated cycles of interaction between myosin heads and actin. 1965-04-10 Actin-Myosin Interaction: Structure, Function and Drug Discovery 1.

The molecular mechanism involves structural transitions at the interface between actin and myosin’s catalytic domain, and within myosin’s light chain domain, which contains binding sites for essential (ELC) and regulatory light chains (RLC). Muscle contraction is resulted from the interaction of myosin with actin and ATP. The study of kinetics of binding of myosin subfragment 1 (S1) to F-actin revealed the two step binding, which were modeled by initial binding of S1 to one actin monomer (state 1) and then to the second neighboring monomer (state 2). ATP is required to disrupt the myosin-actin interaction and prepare the system for another 'oar stroke.' Repetition of these oar-like myosin strokes constitutes a muscle contraction.
