This recombinant Human CYP11A1 protein is an E.coli?expressed protein (Full Length of Mature Protein) with N-terminal 6xHis-SUMO tag?and its purity is 90%+ determined by SDS-PAGE. With the appropriate cDNA and PCR methods, CYP11A1?expression plasmids can be rapidly produced. which must undergo denaturation and folding cycle, can be recovered with more modest yields. Hence, using small-scale fermentations and laboratory-scale processing equipment, CYP11A1 proteins (or subdomains thereof) can usually be produced in sufficient quantities to initiate most studies including detailed structural determinations.which must undergo denaturation and folding cycle, can be recovered with more modest yields.

CYP11A1 is the first and rate-limiting enzyme in the steroidogenic pathway that contributes to the conversion of cholesterol to pregnenolone. It thus plays a major role in the modulation of steroidogenesis. CYP11A1 is primarily expressed in the adrenal cortex. Mutations in the CYP11A1 gene induce steroid hormone deficiency and can lead to lipoid congenital adrenal hyperplasia and are related to primary adrenal insufficiency (PAI) and disorders of sex development (DSD) in 46, XY patients. CYP11A1 is also involved in the development of peanut allergy, modulating peanut-induced allergic responses through effects on steroidogenesis. As a result, CYP11A1 is a unique target for the regulation and therapy of peanut allergy. -

功能：A cytochrome P450 monooxygenase that catalyzes the side-chain hydroxylation and cleavage of cholesterol to pregnenolone, the precursor of most steroid hormones. Catalyzes three sequential oxidation reactions of cholesterol, namely the hydroxylation at C22 followed with the hydroxylation at C20 to yield 20R,22R-hydroxycholesterol that is further cleaved between C20 and C22 to yield the C21-steroid pregnenolone and 4-methylpentanal. Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate and reducing the second into a water molecule. Two electrons are provided by NADPH via a two-protein mitochondrial transfer system comprising flavoprotein FDXR (adrenodoxin/ferredoxin reductase) and nonheme iron-sulfur protein FDX1 or FDX2 (adrenodoxin/ferredoxin).
