  • TEV protease is a catalytic part of the Nuclear Inclusion protein "a" (NIa) from tobacco etch virus (TEV) (1).
  • TEV is a cysteine protease that specifically recognizes and cleaves a linear epitope with general sequence E-X-X-Y-X-Q-(G/S)(2-5) (where X is any amino acid). The cleavage occurs between Q and G/S.The most common sequence is ENLYFQG or ENLYFQS.
  • Resistant to many widly used protein inhibitors like: PMSF, AEBSF, TLCK, E-64, “Complete” protease inhibitor cocktail (Roche).
  • Robust enzyme active in the wide range of different buffers (with NaCl varied from 0 to 0.4 M and in pH from 4 to 9, enzyme tolerates MES, acetate, phosphate, glycerol and sorbitol).
  • Active at 4 to 30°C (the enzyme is 3 times less active at 4°C than at 30°C)(6).
  • Sensitive to some detergents (7).
  • Extremely useful for removing affinity tags from fusion proteins in conditions friendly for target protein.

Unit definition: One unit is the amount of enzyme required to cleave >85% of 3 µg of control substrate (35 kDa fusion protein) in 1 hour at 30oC.

1 x Reaction Buffer: 25 mM Tris-HCl (pH 8.0), 150 mM NaCl, 14 mM β-mercaptoethanol.

Storage Buffer: 0.4 M NaCl, 50 mM Tris-HCl (pH 7.5), 2 mM EDTA, 1 mM DTT, 50% glycerol.

Storage Conditions: Store at –20°C. Protein is stable at least for 9 months.

Quality Control: Protease is greater than 95% single-band pure without non- specific protease contamination.
