KK4A peptide

KK4A peptide, a small peptide derived from the nonstructural protein 4A (NS4A) of Hepatitis C virus (HCV), significantly enhances the catalytic efficiency of the NS3 protease. This peptide serves as a valuable tool for further understanding the function and mechanism of the HCV NS3 protease, thereby advancing research on HCV infections.
