Q99UW8 - HDOX1_STAAM

Protein

Heme oxygenase (staphylobilin-producing) 1

Gene

isdG

Organism
Staphylococcus aureus (strain Mu50 / ATCC 700699)
Status
Reviewed - Annotation score: 4 out of 5- Protein inferred from homologyi
  1. 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
