Ac-Phe-Ala-Ala-Gly-Arg-Lys-pNA, Ac-FAAGRK(pNA)-OH

The peptide Ac-FAAGRK(pNA)-OH, also known as 3/4A, is a Dengue Protease Substrate utilized in research related to the Dengue virus, specifically targeting the NS3 serine protease. This peptide sequence plays a crucial role in investigating the substrate specificity and enzymatic activity of the NS3 protease, which is essential for the maturation of the Dengue virus.

Functionally, the peptide acts as a substrate for the NS3 protease, allowing researchers to study its enzymatic activity and kinetics. By monitoring the cleavage of the peptide substrate, scientists can gain insights into the substrate preferences and determinants of specificity of the NS3 protease, which is valuable for understanding the viral replication process and identifying potential drug targets.

Applications of this peptide extend to drug discovery and development efforts aimed at combating Dengue virus infections. By elucidating the interaction between the NS3 protease and its substrate, researchers can identify inhibitors that disrupt viral maturation, thereby inhibiting viral replication and potentially serving as antiviral drugs. Additionally, the peptide substrate can be used in high-throughput screening assays to identify compounds that interfere with NS3 protease activity, facilitating the discovery of novel antiviral agents.

Beyond its application in Dengue virus research, the peptide substrate may also find utility in studying related flaviviruses or other serine proteases. Its use in elucidating enzymatic mechanisms and substrate specificity extends to broader areas of protease biology and drug discovery.

Overall, the peptide Ac-FAAGRK(pNA)-OH, or 3/4A, serves as a valuable tool for investigating the NS3 protease of the Dengue virus, contributing to our understanding of viral replication mechanisms and facilitating the development of antiviral therapies.
