In doing so, we consider a theory performed earlier [Biophys. Chem., 86 (2000) 79] and generalize it within a nonextensive formalism. The generalized theory provides a method to compare the rotational barriers for different helices in lipid bilayers, accounting for long-range interactions via a parameter which is called "entropic index". The results obtained could lead to point out future experiments which might shed light on lipid-protein interactions. © 2004 Published by Elsevier B.V.EnglishChemistry, PhysicalLipid BilayersMembrane ProteinsMembrane Transport ProteinsModels, ChemicalProtein Structure, SecondaryThermodynamicslipidarticlebilayer membranelipid bilayermathematical computingpriority journalprotein lipid interactionprotein structurerotationtheoretical studyArticle10.1016/j.bpc.2004.05.010
