General Information


DRAVP ID  DRAVPe01406

Peptide Name   NQW (L)

Sequence  ACFPWGNQWCGGK

Sequence Length  13

UniProt ID  No entry found

Source  Synthetic construct



Activity Information


Target Organism  HCV

Assay  Surface plasmon resonance

Activity 

  • [Ref.12951030]Hepatitis C virus(HCV):inhibition of polymerase activity(IC50=37.0 µM).

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  RNA-dependent RNA polymerase

Mechanism  The peptide inhibits the de novo synthesis catalyzed by the enzyme, which suggests that it likely inhibited the formation of a preinitiation complex between the enzyme and the 3′OH end of the linear poly (C) substrate.
