Protein

NADPH--cytochrome P450 reductase

Gene

cprA

Organism
Aspergillus terreus (strain NIH 2624 / FGSC A1156)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

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. Involved in ergosterol biosynthesis.UniRule annotation

Catalytic activityi

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

Cofactori

Protein has several cofactor binding sites:
  • FADUniRule annotationNote: Binds 1 FAD per monomer.UniRule annotation
  • FMNUniRule annotationNote: Binds 1 FMN per monomer.UniRule annotation
