CC   -!- FUNCTION: Heme oxygenase cleaves the heme ring at the alpha methene
CC       bridge to form biliverdin. Biliverdin is subsequently converted to
CC       bilirubin by biliverdin reductase. Under physiological conditions, the
CC       activity of heme oxygenase is highest in the spleen, where senescent
CC       erythrocytes are sequestrated and destroyed. Heme oxygenase 2 could be
CC       implicated in the production of carbon monoxide in brain where it could
CC       act as a neurotransmitter. {ECO:0000250}.
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
