Sequence NQVGD
Sequence Length 5
UniProt ID P27395
Source Synthetic construct(derived from JEV NS3 helicase protein)
Activity Information
Target Organism HCV,WNV,JEV
Assay Helicase assay
Activity
Hemolytic Activity No hemolysis information or data found in the reference(s) presented in this entry
Cytotoxicity No cytotoxicity information found in the reference(s) presented
Binding Target NTPase/helicase
Mechanism The intact enzymatic properties of NS3 are necessary for the virus propagation,which possesses numerous enzymatic activities including RNA stimulated nucleoside triphosphatase (NTPase) and RNA helicase activities. The peptides inhibited the NTPase/helicase by a direct interaction with the enzyme highly probably by a competitive mechanism.
