Catalytic Activity 2 H(2)O(2) = O(2) + 2 H(2)O. {ECO:0000255|PROSITE-ProRule:PRU10013, ECO:0000269|PubMed:7882369}.
Cofactor Name=heme; Xref=ChEBI:CHEBI:30413;
Cofactor Name=NADP(+); Xref=ChEBI:CHEBI:58349;
Disease Acatalasemia (ACATLAS) [MIM:614097]: A metabolic disorder characterized by a total or near total loss of catalase activity in red cells. It is often associated with ulcerating oral lesions. {ECO:0000269|PubMed:2308162}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Function Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide. Promotes growth of cells including T-cells, B-cells, myeloid leukemia cells, melanoma cells, mastocytoma cells and normal and transformed fibroblast cells. {ECO:0000269|PubMed:7882369}.
Ptm The N-terminus is blocked.
Similarity Belongs to the catalase family. {ECO:0000305}.
Subcellular Location Peroxisome.
Subunit Homotetramer.
