Abstract

Come together: A novel method for assembling monomers and controlling structure of a de novo helix bundle protein is described. A guanine (G)-rich oligodeoxynucleotide scaffold forms a hydrogen-bonded DNA quadruplex in the presence of potassium counterions, thereby inducing a helical structure and fourfold stoichiometry in conjugated, amphiphilic peptide sequences. The DNA scaffold shows potential for rapidly assembling designed proteins.
