Target

  • 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.
  • Sequence similarities
    Belongs to the heme oxygenase family.
  • Cellular localization
    Microsome. Endoplasmic reticulum.
