6xHis-TEV Protease

Tobacco Etch Virus (TEV) protease is a cysteine protease that is commonly used to remove fusion tags, including His, GST and MBP, at the N or C termini of recombinant proteins. TEV protease specifically recognizes a seven amino acid sequence Glu-Asn-Leu-Tyr-Phe-Gln-Gly/Ser (ENLYFQG/S) and cleaves between Gln and Gly/Ser under a wide range of conditions.

Recombinant 6xHis-TEV was expressed in E. Coli and purified to near homogeneity. A Ser219Asn (S219N) substitution was introduced that has no effect on TEV protease activity, but inhibits auto-cleavage and thus, stabilizing TEV protease during incubation and long-term storage.

We recommend using 3% supplied TEV protease (w/w) to preform reactions at 4 0C for 12-16 h or at 30 0C for 1-4 h. Depending on specific substrates, TEV protease concentration, incubation time, and reaction temperature should be optimized. 6xHis-TEV can be removed by Ni-NTA resin after incubation.

TEV protease maintains high activity under a wide range of temperatures (4 0C - 30 0C), pH (6.0 - 8.5) and buffers, and in the presence of commonly used protease inhibitors.
