pubmed:abstractText |
The serine protease domain of HCV comprising amino acids 1027-1218 (deltaNS3) was expressed in E. coli with a His tag at its N-terminal end. The protease was purified to apparent homogeneity by a single step affinity chromatography resulting in high yields (approximately 3 mg/l of cultured cells). The deltaNS3 efficiently cleaves a 17-mer peptide corresponding to the NS5A-NS5B junction with kcat/Km = 160 x 10(-3) min(-1) microM(-1) in the presence of NS4A peptide. Our deltaNS3 represents the minimal domain possessing highly active protease of NS3 constructed so far. The deltaNS3 protein also efficiently processed a longer substrate corresponding to NS5A/5B junction (2203-2506 amino acids) that was synthesized by in vitro transcription and translation system.
