TEV Protease

Features

• removal of affinity purification tags such as maltose-binding protein (MBP) or poly-histidine from fusion proteins
• engineered to improve thermal stability and decrease autolysis
• high substrate specificity with no non-specific proteolysis 

1. The optimum sequence for the TEV protease cleavage site is Glu-Asn-Leu-Tyr-Phe-Gln-(Gly/Ser). However, it has been reported that other amino acid residues can be used in the P1´ position instead of Ser or Gly. These alternative P1´ amino acids include Ala, Met, and Cys (1).
2. If the fusion protein sample contains > 2 M urea, > 0.5 M Guanidine hydrochloride, > 50 mM imidazole, pH values below 6 or above 9, or cysteine protease inhibitors then it will be necessary to dialyze the fusion protein before TEV Protease cleavage.
3. TEV protease can be used at high concentrations without the occurrence of non-specific proteolysis.
4. Reactions may be scaled-up linearly to accommodate larger reaction volumes.
