Competitive, reversible, physiological? Inhibition of mitochondrial cytochrome oxidase by nitric oxide

Open access
Cooper, Chris·2003·IUBMB Life

Abstract

In the mid 1990s a number of research groups recognized that mitochondrial oxygen consumption could be reversibly inhibited by nitric oxide at the level of the enzyme cytochrome c oxidase. The inhibition was apparently competitive with respect to the oxygen concentration. This review critically assesses the present state of knowledge as regards the hypothesis that nitric oxide is a competitive, reversible, physiological inhibitor of cytochrome oxidase.

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.
