FunctionSPG1_STRSG Binds to the constant Fc region of IgG with high affinity. Publication Abstract from PubMedBecause proteins play vital roles in life, much effort has been invested in their mimicry by synthetic agents. One approach is to design unnatural backbone oligomers ("foldamers") that fold like natural peptides. Despite success in secondary structure mimicry by such species, protein-like tertiary folds remain elusive. A fundamental challenge underlying this task is the design of a sequence of side chains that will specify a complex tertiary folding pattern on an unnatural backbone. We report here a sequence-based approach to convert a natural protein with a compact tertiary fold to an analogue with a backbone composed of approximately 20% unnatural building blocks but folding behavior similar to that of the parent protein.
