Nano-fiber can be self-assembled by mixing two kinds of proteins. Binding between the two α-helices of one protein and two α-helices of second protein yields a four-helix bundle, which is thermally stable. Coarse grained molecular dynamics simulations and electronic structure calculations are used to provide insight on this system, in particular, around their metal ions.
