General annotation (Comments)

Function

Heme oxygenase cleaves the heme ring at the alpha methene bridge to form biliverdin. Biliverdin is subsequently converted to bilirubin by biliverdin reductase. Under physiological conditions, the activity of heme oxygenase is highest in the spleen, where senescent erythrocytes are sequestrated and destroyed. Exhibits cytoprotective effects since excess of free heme sensitizes cells to undergo apoptosis By similarity.

Catalytic activity

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

Subcellular location

Microsome By similarity. Endoplasmic reticulum membrane By similarity; Peripheral membrane protein; Cytoplasmic side.

Sequence similarities

Belongs to the heme oxygenase family.
