    Functioni

    This enzyme is required for electron transfer from NADP to cytochrome P450 in microsomes. It can also provide electron transfer to heme oxygenase and cytochrome B5. Reduces a variety of substrates in vitro, such as cytochrome c, feericyanide and dichloroindophenol.5 Publications

    Catalytic activityi

    NADPH + n oxidized hemoprotein = NADP+ + n reduced hemoprotein.
