Coiled-Coil Protein Origami: Design, Isolation, and Characterization.

Coiled-coil protein origami (CCPO) is a rationally designed de novo protein fold, constructed by concatenating coiled-coil forming segments into a polypeptide chain, that folds into polyhedral nano-cages. To date, nanocages in the shape of a tetrahedron, square pyramid, trigonal prism, and trigonal bipyramid have been successfully designed and extensively characterized following the design principles of CCPO. These designed protein scaffolds and their favorable biophysical properties are suitable for functionalization and other various biotechnological applications. To further facilitate the development, we are presenting a detailed guide to the world of CCPO, starting from design (CoCoPOD, an integrated platform for designing CCPO strictures) and cloning (modified Golden-gate assembly) to fermentation and isolation (NiNTA, Strep-trap, IEX, and SEC) concluding with standard characterization techniques (CD, SEC-MALS, and SAXS). © 2023.
