Determining structure and action mechanism of LBF14 by molecular simulation

The recently discovered, membrane-active peptide LBF14 contains several non-proteinogenic amino acids and is able to transform vesicles into tubule networks. The exact membrane interaction mechanism and detailed secondary structure are yet to be determined. We performed molecular dynamics simulations of LBF14 and let it fold de novo into its ensemble of native secondary structures. Histidine protonation state effects on secondary structure were...
