WebMay 18, 2001 · To optimize biodevice assembly and cholesterol sensing, recombinant and wild type P450scc cytochromes are extensively characterized both in solution and in thin solid films, using X-ray scattering, Brewster angle microscopy, quartz crystal nanobalance, ellipsometry, cyclic voltammetry, and circular dichroism. WebDec 15, 2010 · The cholesterol side-chain cleavage enzyme (P450scc), encoded by the CYP11A1gene, converts cholesterol to pregnenolone to initiate steroidogenesis. Genetic defects in P450scc cause a rare autosomal recessive disorder that is clinically indistinguishable from congenital lipoid adrenal hyperplasia (lipoid CAH).

WebCytochrome P450scc (P450scc or CYP11A1) catalyses the first enzymatic step of steroid biosynthesis, the cleavage of the side chain of cholesterol to produce pregnenolone in the mitochondrion. The activity of P450scc is dependent upon electron delivery from NADPH-dependent adrenodoxin reductase (AdR), via adrenodoxin (Adx), to the P450scc. WebP450scc is the mitochondrial cholesterol side-chain cleavage enzyme catalyzing the series of reactions formerly termed 20,22-lyase. P450scc is encoded by CYP11A1 gene that is located on chromosome 15q23-q24 and is about 30 kb in length ( Sparkes et al., 1991; Miller and Auchus, 2011). It catalyzes the first step in all steroid biosynthesis and ...
