Overview

This product has been discontinued.





Recombinant, human West Nile virus NS3 proteinase expressed in E. coli as a fusion protein with the cofactor, NS2B, and a C-terminal His•Tag® sequence. Amino acids 1476-1687 of the West Nile polyprotein precursor is fused to amino acids 1393-1440 of NS2B via a 9-amino acid linker (GGGGSGGGG). The C-terminal lysine (Lys48) is mutated to alanine to inactivate autolytic cleavage in and improve stability. It is believed that West Nile Virus protease is an important target for the development of therapeutics that prevent viral replication.
