Dengue 2 virus NS2B and NS3 form a stable complex that can cleave NS3 within the helicase domain.


Flavivirus genomic RNA is translated into a large polyprotein that is processed into structural and nonstructural proteins. The N-termini of several nonstructural proteins are produced by cleavage at dibasic sites by a two-component viral proteinase consisting of NS2B and NS3. NS3 contains a trypsin-like serine proteinase domain at its N-terminus, whereas… (More)
