Investigating conformational changes of Prefoldin β1 as result of applying external mechanical force without any position constraint

In this study, steered molecular dynamics simulation is applied along with the centre of mass pulling and analyses of Prefoldin β1 conformational changes to characterise some of those abilities. Thus, applying external mechanical force without any position constraint shows that it has no movement throughout simulations. This proposes a novel method to capture different sizes and shapes of cargoes. During simulations, each arm was found to be very flexible, allowing it to enlarge its central cavity and capture different cargoes. For a more accurate analysis, the variations in the cavity of nano-actuator are investigated qualitatively and quantitatively with different parameters. Also, the force analysis of the arms can provide us with decent information about the performance of this nano-actuator.
