Design of a Monomeric 23-Residue Polypeptide with Defined Tertiary Structure

Struthers, Mary D., Cheng, Richard P., Imperiali, Barbara·1996·Science

Abstract

Small proteins or protein domains generally require disulfide bridges or metal sites for their stabilization. Here it is shown that the ββα architecture of zinc fingers can be reproduced in a 23-residue polypeptide in the absence of metal ions. The sequence was obtained through an iterative design process. A key feature of the final design is the incorporation of a type II' β turn to aid in β-hairpin formation. Nuclear magnetic resonance analysis reveals that the α helix and β hairpin are held together by a defined hydrophobic core. The availability of this structural template has implications for the development of functional polypeptides.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
