Transmembrane β-peptide helices as molecular rulers at the membrane surface

Authors Kloos M, Sharma A, Enderlein J, Diederichsen U Journal Journal of Peptide Science Citation J Pept Sci. 2021 Jun 2:e3355. Abstract β-Peptides are known to form 14-helices with high conformational rigidity, helical persistence length, and well-defined spacing and orientation regularity of amino acid side chains. Therefore, β-peptides are well
