Pd(en) as a sequence-selective molecular pinch for alpha-helical peptides
A palladium(II)(ethylenediamine) complex was found to selectively stabilize alpha -helix conformation of peptides having two histidine (His) residues at i and i + (3 or 4) positions, whereas the helix conformation of the other peptides having one or two His at different positions is destabilized.
