WebAug 1, 1995 · The four-helix bundle motif occurs in many structural contexts and in proteins that are functionally diverse. The motif can be classified into individual folds on the basis of topological and geometric properties. It has been thoroughly investigated structurally by both nuclear magnetic resonance and x-ray crystallography. Many … Other examples of four-helix bundles include cytochrome, ferritin, human growth hormone, cytokine, and Lac repressor C-terminal. The four-helix bundle fold has proven an attractive target for de novo protein design, with numerous de novo four-helix bundle proteins having been successfully designed by … See more A helix bundle is a small protein fold composed of several alpha helices that are usually nearly parallel or antiparallel to each other.
