Structure and inhibition mechanism of the catalytic domain of human squalene epoxidase

Abstract

Squalene epoxidase (SQLE) is a key enzyme in cholesterol biosynthesis and is a target for hypercholesteremia and cancer drug development. Here the authors present the crystal structures of the human SQLE catalytic domain alone and bound with small molecule inhibitors, which will facilitate the development of next-generation SQLE inhibitors.
