Protein

NADPH--cytochrome P450 reductase

Gene

POR

Organism
Sus scrofa (Pig)
Status
Reviewed-Annotation score: 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.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

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
