General Information


DRAVP ID  DRAVPe01408

Peptide Name   FPWG (L)

Sequence  CFPWGC

Sequence Length  6

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>150 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.
