OSC
Molecular classification
Enzyme, Isomerase, Oxidosqualene mutase/cyclase
01

Overview

2,3-Oxidosqualene cyclase (OSC) is a key enzyme in the biosynthesis of sterols and triterpenes. It catalyzes the cyclization of 2,3-oxidosqualene into various polycyclic products such as lanosterol and cycloartenol, which are precursors for cholesterol and other sterols in animals, fungi, and plants. OSC's activity represents a crucial step in the formation of the steroid nucleus. Inhibitors targeting OSC are being explored for hypocholesterolemic effects as well as antifungal or phytotoxic applications.
