Protein

Heme-degrading monooxygenase

Gene

isdG

Organism
Listeria monocytogenes serotype 4b (strain F2365)
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 biliverdin 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 + 3 AH2 + 3 O2 = biliverdin + Fe2+ + CO + 3 A + 3 H2O.UniRule annotation
