Rev. 2018, 118, 3559-Chemical Reviews about the paradigmatic glycophorin A -helical dimer and also the OmpA -barrel, highlighting the preliminary self-organization with the detergents prior to association with all the protein.443 The authors conclude that starting from a preformed micelle or from a polydisperse detergent remedy, the resulting protein- detergent assemblies are remarkably equivalent, a conclusion also reached in light of their coarse-grained simulations.464 Khandelia and Kaznessis carried out a simulation of ovispirin-1, which was shown to partition towards the surface of your micelle, adopting a conformation and orientation akin to that measured experimentally inside the presence of a lipid bilayer.459 Similarly, in their theoretical investigation in the influenza hemagglutinin fusion peptide, Lague et al. observed a congruent structural behavior with the latter at both the micelle and the lipid bilayer surfaces, notwithstanding a significant improve on the all round solvation and rigidity in the micellar environment.460 In their series of simulations, Kaznessis and co-workers compared systematically insertion of -helical and hairpin antimicrobial 1181226-02-7 Biological Activity peptides in DPC and SDS micelles, and showed that the peptide-detergent interactions are various in zwitterionic and anionic micelles, underscoring the possibility of distinct modes of action in the surface of mammalian and bacterial membranes.461-463 These early simulations paved the strategy to subsequent investigations made possible by the concomitant improvement of force fields and capability to explore longer time scales afforded by massively parallel architectures.349,465-481 Aside from a rich literature investigating MPs in an explicit DPC environment, many studies have considered protein structures resolved experimentally in DPC and simulated within a lipid bilayer. Here, we concentrate on theoretical contributions comparing structures obtained from resolution NMR and from high-resolution crystallography, which depend on distinct solubilizing agents. Kaznessis and co-workers pursued their systematic examination of environmental effects on antimicrobial peptides, comparing from experimental assays and molecular simulations SDS and DPC micelles, and confirm the previously observed distinct modes of action.465,468 To address the function on the peptide sequence on antimicrobial activity, these authors modeled a series of protegrin peptides and report diverse conformational arrangements and insertion depths in DPC micelles.466 In addition they showed that cation- interactions stabilize indolicin in micelles formed by DPC, but not by SDS, resulting in a more ordered backbone together with the former detergent.467 van der Spoel and co-workers have examined the effect of dehydration of a DPC micelle harboring OmpA, mimicking electrospray-ionization experiments, and revealed that when the protein remains structurally intact, the detergent molecules reorganize from a normal micelle to a spatial arrangement wherein the hydrocarbon tails are expelled outward, favoring headgroup-protein interactions.469 In their theoretical investigation of glycophorin A, Mineev et al. delved into the part played by the surroundings on -helix dimerization, applying DPC micelles and DMPC-DHPC bicelles, and showed that the overall architecture.
