WebApr 1, 2012 · Myosins contain actin- and ATP-binding sites in their conserved catalytic head domains. Conformational changes associated with nucleotide binding, hydrolysis and product release are crucial for the productive motility of myosin enzymes. In the absence of nucleotide and in the ADP-bound state, the head interacts strongly with actin. WebMyosin functions as an ATPase utilizing ATP to produce a molecular conformational change of part of the myosin and produces movement. Movement of the filaments over each other happens when the globular heads protruding from myosin filaments attach and interact with actin filaments to form crossbridges.
