Consequently, we noticed that after a trajectory with three consecutive refolding events of FoxP1-L-FoxP1, there always occurs an unfolding trajectory with three unfolding events when the same ... WebJan 1, 2024 · Whereas static structural prediction is garnering much interest, there is less focus on protein dynamics. Although information about folding can be obtained by Cryo-EM, the knowledge of protein folding from optical tweezers can be used to build models of not only protein structure but also structural transitions. phil keaggy strong tower
