additional information Dengue virus The NS3 protein physically associates with the NS5 polymerase, NS3 andNS5 carry out all the enzymatic activities needed for polyprotein processing and genome replication. NS3 possesses an ATPase/helicase and RNA triphosphatase at its C-terminal end that are essential for RNA replication. In addition to its known enzymatic functions, the NS3 protein appears to be involved in the assembly of an infectious flaviviral particle, through its interactions with NS2A and presumably host cell proteins ?

ATP + H2O ATPase activity, ATP binding mode, the ATP binding site is housed between these two subdomains. In the ATP binding pocket, a Mg ion is coordinated in a octahedral manner by the beta- and gamma-phosphate oxygen atoms from ATP, two equatorial water molecules and oxygen atoms from residues Glu285 in motif II, and Thr200 in motif I, overview Dengue virus ADP + phosphate
