CC   -!- FUNCTION: Allows bacterial pathogens to use the host heme as an
CC       iron source. Catalyzes the oxidative degradation of the heme
CC       macrocyclic porphyrin ring to the biliverdin in the presence of a
CC       suitable electron donor such as ascorbate or NADPH--cytochrome
CC       P450 reductase, with subsequent release of free iron.
CC       {ECO:0000255|HAMAP-Rule:MF_01272}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=heme b + 3 O2 + 3 reduced [NADPH--hemoprotein reductase]
CC         = biliverdin IXalpha + CO + Fe(2+) + H(+) + 3 H2O + 3 oxidized

CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01272}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01272}.
CC   -!- SIMILARITY: Belongs to the antibiotic biosynthesis monooxygenase
CC       family. Heme-degrading monooxygenase IsdG subfamily.
