TEV protease, encoded by the Tobacco Etch Virus (TEV), is a 27 kDa catalytic domain of the Nuclear Inclusion a (NIa) protein encoded by the virus (TEV). It is widely used for cleaving fusion proteins because of its sequence specificity. It recognizes a linear epitope of the general form E-Xaa-Xaa-Y-Xaa-Q-(G/S). Cleavage occurs between Q and G or Q and S. The structure of TEV protease is similar to that of of the serine protease family. Like serine proteases, TEV protease utilizes a catalytic triad of residues to hydrolyze peptide bonds. The distinguishing feature of TEV protease, however, is that instead of the serine nucleophile in the triad Ser-Asp-His, there is a cysteine, which may explain the resistance of TEV protease to protease inhibitors which are commonly used. The strain used is the auto inactivation-resistant mutant S219V. The catalytic activity of the S219V mutant is approximately 2 fold greater than that of the wild-type protease.

Store vial at -20° C or below prior to opening. This vial contains a relatively low volume of reagent (25 µL). To minimize loss of volume dilute 1:10 by adding 225 µL of the buffer stated above directly to the vial. Recap, mix thoroughly and briefly centrifuge to collect the volume at the bottom of the vial. Use this intermediate dilution when calculating final dilutions as recommended below. Store the vial at -20°C or below after dilution. Avoid cycles of freezing and thawing.
