Superoxide radical inhibits catalase.

Open access
Kono, Y, Fridovich, I·1982·Journal of Biological Chemistry

Abstract

Catalase was inhibited by a flux of O2- generated in situ by the aerobic xanthine oxidase reaction. Two distinct types of inhibition could be distinguished. One of these was rapidly established and could be as rapidly reversed by the addition of superoxide dismutase. The second developed slowly and was reversed by ethanol, but not by superoxide dismutase. The rapid inhibition was probably due to conversion of catalase to the ferrooxy state (compound III), while the slow inhibition was due to conversion to the ferryl state (compound II). Since neither compound III nor compound II occurs in the catalatic reaction pathway, they are inactive. This inhibition of catalase by O2- provides the basis for a synergism between superoxide dismutase and catalase. Such synergisms have been observed in vitro and may be significant in vivo.

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.
