Heteromeric Three-Stranded Coiled Coils Designed Using a Pb(II)(Cys)3 Template Mediated Strategy

Our latest Metallopeptide paper showing how it is possible to form pure heterotrimeric three-stranded coiled coils by combining three distinct characteristics: (1) a cysteine sulfur layer for metal coordination, (2) a thiophilic, trigonal pyramidal metalloid (Pb(ii)) that binds to these sulfurs and (3) an adjacent layer of reduced steric bulk generating a cavity where water can hydrogen bond to the cysteine sulfur atoms.
