Molecular recognition with designed peptides and proteins.
The design of proteins and peptides as molecular receptors is a rapidly growing area of research. Two primary approaches have been utilized, involving the minimization of known protein binding motifs or the de novo design of binding pockets within well-folded protein structures. These approaches are complementary and help define the minimum requirements necessary for biomolecular recognition. Recent advances in this area include the design of cavities within helix bundles for the binding of anesthetics, the design of beta-hairpins for the recognition of nucleotides and oligonucleotides, the redesign of protein binding sites for unique ligands, and the design of mini-proteins via protein grafting for the recognition of proteins and DNA. These advances provide exciting new opportunities to develop novel biosensors, de novo designed catalysts, exogenously triggered synthetic signal transduction cascades, and novel approaches to therapeutic treatments.
