Trapping Oxidative Folding Intermediates During Translocation to the Intermembrane Space of Mitochondria: In Vivo and In Vitro Studies

Sideris, Dionisia P., Tokatlidis, Kostas·2010·Methods in Molecular Biology

Abstract

The MIA40 pathway is a novel import pathway in mitochondria specific for cysteine-rich proteins of the intermembrane space (IMS). The newly synthesised precursors are trapped in the IMS by a disulfide relay mechanism that involves introduction of disulfides from the sulfhydryl oxidase Erv1 to the redox-regulated import receptor Mia40 and then on to the substrate. This thiol-disulfide exchange mechanism is essential for the import and oxidative folding of the incoming cysteine-rich substrate proteins. In this chapter we will describe the experimental methods that have been developed in order to study and characterise disulfide-trapped intermediates in yeast mitochondria.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The FAD-containing sulfhydryl oxidase Erv1 maintains the intermembrane protein Mia40 in an oxidized form.

    “A crucial component of this system is the FAD-containing sulfhydryl oxidase Erv1, which maintains the intermembrane protein Mia40 in an oxidized form (40, 391).”

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.
