These force spectroscopy experiments have shown that many water-soluble and membrane proteins unfold via one or more intermediates. Recently, Li and co-workers found a linear correlation between the unfolding force of the native state and the intermediate in fibronectin, which they suggested indicated the presence of a molecular memory or multiple unfolding pathways (1). Here, we apply two independent methods in combination with Monte Carlo simulations to analyze the unfolding of α-helices E and D of bacteriorhodopsin (BR). We show that correlation analysis of unfolding forces is very sensitive to errors in force calibration of the instrument. In contrast, a comparison of relative forces provides a robust measure for the stability of unfolding intermediates. The proposed approach detects three energetically different states of α-helices E and D in trimeric BR. These states are not observed for monomeric BR and indicate that substantial information is hidden in forced unfolding experiments of single proteins.","lang":"eng"}],"title":"Complex stability of single proteins explored by forced unfolding experiments","date_created":"2018-12-11T12:03:13Z","date_updated":"2021-01-12T07:43:19Z","author":[{"full_name":"Harald Janovjak","first_name":"Harald L","orcid":"0000-0002-8023-9315","id":"33BA6C30-F248-11E8-B48F-1D18A9856A87","last_name":"Janovjak"},{"first_name":"Tanuj","last_name":"Sapra","full_name":"Sapra, Tanuj K"},{"full_name":"Mueller, Daniel J","last_name":"Mueller","first_name":"Daniel"}],"intvolume":"        88","quality_controlled":0,"doi":"10.1529/biophysj.105.059774","year":"2005","day":"01","_id":"3416","page":"37 - 39","issue":"5"}
