Cover picture: The opioid peptide dynorphin A-(1-17) in DMPC bilayers at the end of 2-ns molecular dynamics simulations. Two independent simulations from different starting points converged to the same tilted orientation preferred by dynorphin in the bilayers. The highlighted lipids are defined as contact lipids that have at least one atom within 5 Å of the dynorphin helix region. Note that contact lipids from the bottom layer have moved ~1 Å toward the center of the bilayer. See the article by Sankararamakrishnan and Weinstein on p. 2331.
