Mechanistic Studies of the Oxidation of Isoniazid by the Catalase Peroxidase from Mycobacterium tuberculosis
Open accessAbstract
The enzymic oxidn. of isoniazid by the catalase-peroxidase of Mycobacterium tuberculosi was studied. The reaction products suggest two reaction pathways involving both electrophilic and radical species. Labeling expts. are consistent with a reaction mechanism involving the formation of an acyldiimide intermediate followed by decompn. to the corresponding aldehyde and peracid. The results suggest that isoniazid is oxidized by the catalase-peroxidase to a reactive species that may act by inactivating an essential enzyme of M. tuberculosis. [on SciFinder (R)]

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.
