Comments

Comment Type Description
Catalytic Activity 2 reduced adrenodoxin + NADP(+) = 2 oxidized adrenodoxin + NADPH.
Cofactor Name=FAD; Xref=ChEBI:CHEBI:57692;
Function Serves as the first electron transfer protein in all the mitochondrial P450 systems. Including cholesterol side chain cleavage in all steroidogenic tissues, steroid 11-beta hydroxylation in the adrenal cortex, 25-OH-vitamin D3-24 hydroxylation in the kidney, and sterol C-27 hydroxylation in the liver.
Pathway Steroid metabolism; cholesterol metabolism.
Similarity Belongs to the ferredoxin--NADP reductase type 1 family
Subcellular Location Mitochondrion matrix.
Subunit Monomer. Interacts directly with FDX1
