popc lipid tm
Given the TM α-helical conformation of pHLIP in state III, these distances suggest that the C terminus is buried in the head group layer of inner leaflet lipids, supporting the notion that pHLIP in state III is barely long enough to be TM (30).

Epub ahead of print. doi: 10.1083/jcb.201907098. 4 shows the exemplary pH-dependent spin−lattice (T1; Fig. In addition, to gain critical insights on pHLIP insertion from the perspective of the membrane, advanced ssNMR techniques were applied to study lipid dynamics (at different timescales and throughout the entire insertion pH range). 2020 Apr 14;10(4):39. doi: 10.3390/life10040039. Based on the new findings, we propose a multistage pHLIP insertion model with distinct protonation-state intermediates. 0000005546 00000 n endstream endobj 145 0 obj <> endobj 146 0 obj <> endobj 147 0 obj <> endobj 148 0 obj <> endobj 149 0 obj <. Membrane stability in the presence of methacrylate esters. Epub 2020 Jun 15. Previously, we hypothesized that such thermodynamic intermediate states differ from each other, as well as the initial and end states, by the protonation status of several D/E residues (30). S1) over time, along with simulated curves denoting the best-fit distances, are shown for (A) pH 7.4 and (C) pH 5.3.

Moreover, we proved that such QD-modified liposomes formed supported lipid bilayers and their final structure depended on the type of underlying cushion.

Characterization of a membrane binding loop leads to engineering botulinum neurotoxin B with improved therapeutic efficacy. Thrombocidin-1-derived antimicrobial peptide TC19 combats superficial multi-drug resistant bacterial wound infections. In terms of structure, at pH 5.3, pHLIP adopts α-helical conformation in residues A10−T18 and L21−A32 (30). 2020 Apr 21;36(15):4071-4079. doi: 10.1021/acs.langmuir.0c00456.
