Dipicolylglycyl-phenylalanine zinc(II): a metallopeptide with a built-in conformational switch and its homochiral helical coordination polymer.
The peptide-zinc complex [(Dpg-Phe)Zn]2+ (Dpg = N,N-dipicolylglycine; Phe = phenylalanine) reversibly forms a homochiral P-helical coordination polymer upon switching the pH from mildly basic to mildly acidic.
