Definice

Enzym P450 závislý na NADPH, který hraje zásadní roli v biosyntetické dráze sterolů tím, že katalyzuje demethylaci 14-methylsterolů, jako např. lanosterolu. Enzym působí cestou opakované hydroxylace 14-methylové skupiny, což vede k její postupné přeměně na alkohol, aldehyd a poté na karboxylát, který je odstraněn jako kyselina mravenčí. Sterol-14-demetyláza je neobvyklým cytochromem P450, protože se nachází v široké škále organismů včetně živočichů, rostlin, hub a prvoků.

An NADPH-dependent P450 enzyme that plays an essential role in the sterol biosynthetic pathway by catalyzing the demethylation of 14-methyl sterols such as lanosterol. The enzyme acts via the repeated hydroxylation of the 14-methyl group, resulting in its stepwise conversion into an alcohol, an aldehyde and then a carboxylate, which is removed as formic acid. Sterol 14-demethylase is an unusual cytochrome P450 enzyme in that it is found in a broad variety of organisms including ANIMALS; PLANTS; FUNGI; and protozoa.
