Conformational shift in the closed state of GroEL induced by ATP-binding triggers a transition to the open state

GroEL is a chaperonin that undergoes a conformational change from a closed state to an open state. This change requires ATP, but does not require ATP hydrolysis. To investigate the role of ATP in the conformational change, we conducted computer simulations using Elastic Network Model. We found that an ATP molecule behaves as a blockage that induces a population shift and increases the population of conformation that can lead to the open state conformation and decreases the population of conformation that cannot reach the open state conformation.
