Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity (By similarity). May be involved in protection from the host during host infection. AH2 + H2O2 = A + 2 H2O 2 H2O2 = 2 H2O + O2 Binds 1 heme b (iron(II)-protoporphyrin IX) group per monomer. Homodimer or homotetramer. Induced by temperature shift to 37 degrees Celsius, the condition whereby the pathogenic yeast phase is formed. Formation of the three residue Trp-Tyr-Met cross-link is important for the catalase, but not the peroxidase activity of the enzyme. Belongs to the peroxidase family. Peroxidase/catalase subfamily.
