Abstract

Minimalistic peptides composed of d- and l-amino acids are attractive building blocks for functional supramolecular materials, including catalysts. d-Amino acids have long been known to promote turn conformations in peptides, yet unexpected twists continue to emerge on their effects on self-assembly. The combination of single-crystal X-ray diffraction and full-atom molecular dynamics have finally unraveled fine details of how l-d-l-tripeptides visit different conformations in solution and establish key interactions in supramolecular structures.
