The cofactor 4A residues 990-1000(GLY SER VAL VAL ILE VAL GLY ARG ILE ASN LEU) in this entry correspond to residues numbering 1678-1688 of database sequence reference (UNP A8DG50). This peptide is covalently linked to the N-terminus of NS3. C1679S mutation was engineered to prevent disulfide formation. The V1686I and I1687N were engineered to optimize the linker between the cofactor 4A and NS3.
