Here, we report on a novel lipid membrane mimetic based on peptoid belts. The peptoids, composed of 15 residues, were synthesized by alternating N-(2-phenethyl)glycine with N-(2-carboxyethyl)glycine residues at a 2:1 molar ratio. The chemically synthesized peptoids possess a much lower degree of polydispersity versus styrene-maleic acid polymers, thus yielding uniform discs. Moreover, the peptoid oligomers are more flexible and do not require a specific folding, unlike lipoproteins, in order to wrap around the hydrophobic membrane core. The NMR spectra measured for the membrane-bound form of Pf1 coat protein incorporated in this new lipid mimetics demonstrate a higher order parameter and uniform linewidths compared with the conventional bicelles and peptide-based macrodiscs. Importantly, unlike bicelles, the peptoid-based macrodiscs are detergent free.}, number={17}, journal={BIOPHYSICAL JOURNAL}, author={Galiakhmetov, Azamat R. and Davern, Carolynn M. and Esteves, Richard J.
