| Protein existence | Inferred from homology. |
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 in the presence of a suitable electron donor such as ascorbate or NADPH--cytochrome P450 reductase, with subsequent release of free iron By similarity. |
| Catalytic activity | Heme + 3 AH2 + 3 O2 = biliverdin + Fe2+ + CO + 3 A + 3 H2O. HAMAP MF_01272 |
| Subunit structure | Homodimer By similarity. |
| Subcellular location | Cytoplasm By similarity. |
| Sequence similarities | Belongs to the antibiotic biosynthesis monooxygenase family. Heme-degrading monooxygenase isdG subfamily. |
