WebHere we used single-molecule optical tweezers to investigate the folding–unfolding pathways of full length Top7 as well as its C-terminal fragment (CFr) in different sequence environments. Our results showed that the mechanical folding of Top7 involves an intermediate state that likely involves non-native interactions/structure. WebAn optical tweezer uses the forces exerted by a strongly focused beam of light to trap, manipulate, and transform a small volume of matter. Originally introduced by Bell Labs researchers in 1986, optical tweezers have become indispensible tools for research in physics, chemistry and biology.
