Microbiology 145:549-559(1999).

Comments

FUNCTION: Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity.
CATALYTIC ACTIVITY: 2 H₂O₂ = O₂ + 2 H₂O.
CATALYTIC ACTIVITY: Donor + H₂O₂ = oxidized donor + 2 H₂O.
COFACTOR: Binds 1 heme B (iron-protoporphyrin IX) group per dimer.
SUBUNIT: Homodimer.
PTM: The covalent Trp-Tyr-Met adduct is important for the catalase, but not the peroxidase activity of the enzyme (By similarity).
SIMILARITY: Belongs to the peroxidase family. Peroxidase/catalase subfamily.
