<span>Since muscle contraction depends on interactions between actin, myosion and some intermediate molecules, the primary protein structure of such proteins and their spatial conformation are fundamental for their functioning. For example, actin and myosin, both filamentous proteins that slide past each other or troponin/tropomyosin interactions that blocks the binding of myosin to actin.</span>
