title: Peptide translocators with engineered dehydration-prone hydrogen bonds.
abstract: The unfavorable crossing of cell membranes by water-soluble peptides poses a challenge to peptide-based drug delivery. Thus the authors engineered a conformational switch that modulates cellular translocation. The peptide design hinges on dehydration propensities of hydrogen bonds that form to mitigate polar-group internalization penalties and is experimentally corroborated through cell-internalization assays.
