Protein

Heme oxygenase (staphylobilin-producing) 1

Gene

isdG

Organism
Staphylococcus aureus (strain COL)
Status
Reviewed - Annotation score: 4 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
