Peptide Sequence Features that Reduce Membrane Pore Line Tension

Together, these results link peptide sequence to pore-rim localization, lipid reorganization, and ultimately line-tension reduction, providing molecular design principles for α-helical peptides that stabilize permeable membrane states.

Quantitative Mapping of Glycosaminoglycan Secondary Structure Driven by Sulfation and Iduronic Acid.

This work employs large-scale all-atom molecular dynamics simulations to investigate the molecular origin of secondary structure in sulfated GAGs and introduces a two-parameter structural metric that objectively classifies GAG secondary structures and distinguishes heparin helices from related conformations.
