Catalase-peroxidase

UniProtKB accession:  P9WIE5

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity, oxidizing various electron donors including NADP(H) (PubMed:18178143, PubMed:9006925). Protects M.tuberculosis against toxic reactive oxygen species (ROS) including hydrogen peroxide as well as organic peroxides and thus contributes to its survival within host macrophages by countering the phagocyte oxidative burst (PubMed:15165233, PubMed:8658136). Also displays efficient peroxynitritase activity, which may help the bacterium to persist in macrophages (PubMed:10080924).
