ABSTRACT
Single-molecule magnetic tweezers have recently been adapted for monitoring the interactions between transmembrane helices of membrane proteins within lipid bilayers. In this chapter, we describe the procedures of conducting studies on membrane protein folding using a robust magnetic tweezer method. This tweezer method is capable of observing thousands of (un)folding transitions over extended periods of several to tens of hours. Using this approach, we can dissect the folding pathways of membrane proteins, determine their folding time scales, and map the folding energy landscapes, with a higher statistical reliability. Our robust magnetic tweezers also allow for estimating the folding speed limit of helical membrane proteins, which serves as a link between the kinetics and barrier energies.
