Protein
Heme-degrading monooxygenase
Gene
isdG, BA_4782, GBAA_4782, BAS4437
Organism
Bacillus anthracis
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

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 By similarity.1 Publication

Catalytic activityi

Protoheme + 3 AH2 + 3 O2 = biliverdin + Fe2+ + CO + 3 A + 3 H2O.1 Publication
