Steroid hormones are important regulators of many physiological processes. The steroid precursor pregnenolone is converted through several enzymatic steps into all types of steroids, including the stress hormone cortisol. Mitochondrial steroidogenic cytochrome P450 (CYP) enzymes crucially relying on electron transfer from the redox partner ferredoxin (FDX1) are involved in key steps of the cortisol biosynthesis pathway.Cortisol is well-known regulator of...
