General annotation (Comments)

Function

Allows bacterial pathogens to use the host heme as an iron source. Catalyzes the oxidative degradation of the heme macrocyclic porphyrin ring to the oxo-bilirubin chromophore staphylobilin (a mixture of the linear tetrapyrroles 5-oxo-delta-bilirubin and 15-oxo-beta-bilirubin) in the presence of a suitable electron donor such as ascorbate or NADPH--cytochrome P450 reductase, with subsequent release of free iron By similarity. HAMAP-Rule MF_01272

Catalytic activity

Protoheme + 3 AH2 + 3 O2 = staphylobilin + Fe2+ + CO + 3 A + 3 H2O. HAMAP-Rule MF_01272

Subunit structure

Homodimer By similarity. HAMAP-Rule MF_01272

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_01272.

Sequence similarities

Belongs to the antibiotic biosynthesis monooxygenase family. Heme-degrading monooxygenase IsdG subfamily.
