WebAug 20, 2009 · Introduction. Polyproline can form either type I (PPI) or type II (PPII) helices. PPI is a right-handed helix containing all cis peptide bonds and adopts backbone dihedral angles of (ϕ, ψ, ω) = (−75°, 160°, 0°).. Unlike α-helices and β-sheets, there are no characteristic main chain hydrogen bonding patterns in PPI and PPII helices making it … WebThe crystals belonged to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a=24.79, b=37.23, c=62.95 A.

WebOct 20, 2024 · Peptoids, N-substituted glycine oligomers, are an important class of foldamers that can adopt polyproline-type helices (PP-I and PP-II), given that the majority of their sequence consists of chiral, bulky side chains. Herein a new approach for the stabilization of a pure PP-I-like peptoid helix through metal coordination is introduced.
