Function
- in association with cyt P450 reductase & bilirubin reductase, cleaves heme to form bilirubin, CO & Fe+2
- electrons donated by NADPH via cyt P450 reductase
- biliverdin reductase rapidly reduces biliverdin to bilirubin
heme oxygenase
cyt P450 reductase
heme[Fe+2] + O2 ------------------> biliverdin + CO + Fe+2
+ NADPH + H+ + NADP+ + H2O
biliverdin reductase biliverdin ------------------> bilirubin + NADP+ + NADPH + H+
