Protein

Heme oxygenase (staphylobilin-producing) 2

Gene

isdI

Organism
Staphylococcus aureus (strain MSSA476)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

Protoheme + 4 AH2 + 4 O2 = 5-oxo-delta-bilirubin + Fe2+ + CO + 4 A + 4 H2O.UniRule annotation
Protoheme + 4 AH2 + 4 O2 = 15-oxo-beta-bilirubin + Fe2+ + CO + 4 A + 4 H2O.UniRule annotation
