Abstract

The three-dimensional structure of the electron transport protein thioredoxin-S2 from E. coli has been determined from a 2.8 A resolution electron density map. The molecule is built up of a central core of three parallel and two antiparallel strands of pleated sheet surrounded by four helices. Thr residues involved in the active center 14-membered disulfide ring of thioredoxin form a protrusion between one of the helices and the middle strand of the pleated sheet. This region of the molecule, comprising two parallel strands joined by the protrusion and a helix, is structurally very similar to corresponding functionally important regions in the nucleotide-binding domains of flavodoxin and the dehydrogenases. The molecule has about 75% of the residues in well-defined secondary structures. The structure indicates that the carboxy-terminal third of the molecule forms an independent folding unit consisting of two strands of antiparallel pleated sheet and a terminal alpha-helix. This agress with the noncovalent reconstitution experiments from thioredoxin peptide fragments. Thioredoxin is an example of a protein with the active center located on a protrusion rather than in a cleft, thus demonstrating the existence of male proteins.

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.
