Overexpression, Purification and Functional Characterisation of Wild-Type HIV-1 Subtype C Protease and Two Variants Using a Thioredoxin and His-Tag Protein Fusion System.

Abstract excerpt

In recent years, various strategies have been used to overexpress and purify HIV-1 protease because it is an essential drug target in anti-retroviral therapy. Obtaining sufficient quantities of the enzyme, however, remains challenging. Overexpression of large quantities is prevented due to the enzyme's autolytic nature and its inherent cytotoxicity in Escherichia coli cells. Here, we describe a novel HIV-1...
