RTEV protease (reorganization) is a restructuring protease after genetic engineering transformation, the enzyme-specific sexual sex Glu-Asn-Leu-Tyr-PHE-GLN-GLY sequence. Compared with proteases such as intestinal kinase U (EK) U (EK), THROMBIN, Factorxa, Sumo, it has the dual characteristics of high activity and high -specificity. Because of high shear activity and specificity, RTEV protease has become a fusion protein. After expression, remove the preferred protease of fusion TAG. The enzyme is purified by 6 × HIS tags (including the arcered acid tags), and the purity is 99 %. Purpose of purifying the purpose of protein.

Common factor affecting natural TEV enzyme activity: 1) PMSF and AEBSF (1 mm), TLCK (1 mm), Bestatin (1 mg/ml), Pestatin A ( 1 mm), EDTA (1 mm), and E-64 (3 mg/ml). The above protease inhibitors have no effect on the activity of RTEV; 2) Zn ion (\u003e 5 mm) inhibit the activity of RTEV; 3) and and and and and. The reagent of cysteine \u200b\u200breaction is also a potential inhibitor of RTEV.
