Recombinant Human LSS, N-His

Introduction

Recombinant Human LSS, also known as Lanosterol Synthase, is a key enzyme involved in the biosynthesis of cholesterol. This enzyme is encoded by the LSS gene and is responsible for the conversion of squalene to lanosterol, a critical step in the cholesterol synthesis pathway. In recent years, recombinant Human LSS has gained significant attention in the field of biotechnology and pharmaceutical research due to its potential applications in drug discovery and development. In this article, we will provide a comprehensive overview of the structure, activity, and applications of recombinant Human LSS.

Structure of Recombinant Human LSS

Recombinant Human LSS is a homodimeric protein consisting of two identical subunits, each with a molecular weight of approximately 60 kDa. The crystal structure of recombinant Human LSS has been determined, revealing a three-dimensional arrangement of alpha-helices and beta-sheets. The active site of the enzyme is located in a deep pocket at the interface of the two subunits and is composed of conserved amino acid residues essential for catalytic activity.

Activity of Recombinant Human LSS

The primary function of recombinant Human LSS is to catalyze the cyclization of squalene, a linear hydrocarbon, to form lanosterol, a tetracyclic sterol. This reaction involves a series of complex steps, including the formation of carbocations and the rearrangement of chemical bonds. Recombinant Human LSS is highly specific for squalene and has a high turnover rate, making it an efficient catalyst in the cholesterol biosynthesis pathway.
