Function
[KATG_MYCTU] Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity. Displays also NADH oxidase, isoniazid (INH) lyase and isonicotinoyl-NAD synthase activity. May play a role in the intracellular survival of mycobacteria. May be involved in DNA repair. Partly complements recA-deficient E.coli cells exposed to UV radiation, mitomycin C or hydrogen peroxide. Increases resistance to mitomycin C in E.coli cells deficient for either uvrA, uvrB or uvrC.[1]
