Dengue Protease Substrate Recognition: Binding of the Prime Side.

ABSTRACT: Dengue virus (DENV), transmitted predominantly in tropical and subtropical regions by the mosquito Aedes aegypti, infects millions of people and leads to dengue fever and thousands of deaths each year. There are no direct-acting antivirals to combat DENV, and molecular and structural knowledge is required to develop such compounds. The dengue NS2B/NS3 protease is a promising target for direct-acting antivirals, as viral polyprotein cleavage during replication is required for the maturation of the viral particle. The NS2B/NS3 protease processes 8 of the 13 viral polyprotein cleavage sites to allow viral maturation. Although these sites share little sequence homology beyond the P1 and P2 positions, most are well conserved among the serotypes. How the other substrate residues, especially at t
