Protein

NADPH--cytochrome P450 reductase

Gene

POR

Organism
Oryctolagus cuniculus (Rabbit)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

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.

Catalytic activityi

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

Cofactori

FAD.
FMN.
