The motor domain operates by converting the chemical energy stored in ATP into mechanical work. This process involves several steps: 1. ATP Binding: The motor domain binds to ATP, causing a conformational change in the protein. 2. ATP Hydrolysis: The ATP is hydrolyzed into ADP and inorganic phosphate, releasing energy. 3. Conformational Change: The energy released induces further conformational changes, resulting in the movement of the motor protein along its respective filament. 4. Release and Reset: ADP is released, and the motor domain resets to bind another ATP molecule, repeating the cycle.
