Acting on iron-sulfur proteins as donors;
With NAD+ or NADP+ as acceptor
BRITE hierarchy
Sysname
reduced adrenodoxin:NADP+ oxidoreductase
Reaction(IUBMB)
2 reduced adrenodoxin + NADP+ + H+ = 2 oxidized adrenodoxin + NADPH [RN:
R10159 ]
Reaction(KEGG)
Substrate
Product
Comment
A flavoprotein (FAD). The enzyme, which transfers electrons from NADPH to adrenodoxin molecules, is the first component of the mitochondrial cytochrome P-450 electron transfer systems, and is involved in the biosynthesis of all steroid hormones.
