Protein: NADPH--cytochrome P450 reductase 3 (CPR) (P450R) (EC 1.6.2.4) (Q653S9)
Organism: Oryza sativa subsp. japonica (Rice)
Function: This enzyme is required for electron transfer from NADP to cytochrome P450 in microsomes (By similarity). It can also provide electron transfer to heme oxygenase and cytochrome B5 (By similarity).
Subcellular location: Endoplasmic reticulum membrane {ECO:0000255|HAMAP-Rule:MF_03212, ECO:0000269|PubMed:23053415}; Single-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_03212}; Cytoplasmic side {ECO:0000255|HAMAP-Rule:MF_03212}.
