SOLUTION STRUCTURE OF A DE NOVO DESIGNED SINGLE CHAIN THREE-HELIX BUNDLE (A3D)
Overview
Although de novo protein design is an important endeavor with implications, for understanding protein folding, until now, structures have been, determined for only a few 25- to 30-residue designed miniproteins. Here, the NMR solution structure of a complex 73-residue three-helix bundle, protein, alpha3D, is reported. The structure of alpha3D was not based on, any natural protein, and yet it shows thermodynamic and spectroscopic, properties typical of native proteins. A variety of features contribute to, its unique structure, including electrostatics, the packing of a diverse, set of hydrophobic side chains, and a loop that incorporates common, capping motifs. Thus, it is now possible to design a complex protein with, a well defined and predictable three-dimensional structure.
