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 biliverdin 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 = biliverdin + 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.
