The asymmetric unit contains a dimer of the NS3-NS4a complex. This is only the protease domain of NS3 and a peptide of NS4a. This dimeric structure is the result of the soultion structure of the domain. The full length NS3 contains a 3-domain helicase as well and would not have the same dimeric interfaces.

Preloaded 2-chlorotrityl chloride resin or Wang resin was used for the solid phase assembly of NS4A activator peptide. The sequence of the peptide was Lys-Lys-Gly-Ser-Val-Val-Ile-Val-Gly-Arg-Ile-Ile-Leu-Ser-Gly-Arg-Pro-Ala-Ile-Val-Pro-Lys-Lys-OH. Trifunctional residue sidechain protecting groups included tert-butyl for Ser, tert-butoxycarbonyl for Lys, and 2,2,4,6,7-pentamethyldihydrobenzofuran-5-sulfonyl for Arg. Cleavage and sidechain deprotection was accomplished using 92.5% trifluoroacetic acid, with 2.5% each of water, ethanedithiol and triisopropylsilane for 2 hours. The peptide was purified by reversed phase HPLC. The peptide molecular weight was confirmed by electrospray ionization mass spectrometry. 参照: UniProt: Q9ELS8, UniProt: P26664*PLUS
