Purification and Characterisation of a Pore Protein of the Outer Mitochondrial Membrane from Neurospora crassa
Open accessAbstract
The major protein of the outer mitochondrial membrane of Neurospora was purified. On dodecylsulfate‐containing gels it displayed a single bend with an apparent molecular weight of 31000. reconstitution experiments with artifical lipid bilayers showed that this protein forms pores. Pore conductance was dependent on the voltage across the membrane. The protein inserted into the membrane in an oriented fashion, the membrane current being dependent on the sign of the voltage. Single pore conductance was 5nS, suggesting a diameter of 2nm of the open pore. This mitochondrial protein shows a number of similarities to the outer membrane porins of gram‐negative bacteria.

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.
