1 Quantum-Mechanical/Molecular-Mechanical Studies of CYP11A1-Catalyzed Biosynthesis of Pregnenolone from Cholesterol Reveal a C-C Bond Cleavage Reaction That Occurs by a Compound I-Mediated Electron Transfer. Pregnenolone cytochrome P450 family 11 subfamily A member 1 Homo sapiens
2 The question concerns the mechanism of steroid hormone biosynthesis, whereby the P450 enzyme, CYP11A1, catalyzes the C20-C22 bond-cleavage in the 20,22-hydroxylated cholesterol, 20R,22R-DiOHCH, leading to pregnenolone, which is critical for the subsequent production of all steroid hormones. Pregnenolone cytochrome P450 family 11 subfamily A member 1 Homo sapiens
