pETTev
Allows expression of N-terminally His-tagged TEV protease in E. coli. Ref: Protein Eng. 14:993-1000 (2001)
TEV protease recognition sequence: ENLYFQ↓G
- Please note that this construct is NOT the same as pS219V
- T7lac promoter
- low copy
- Kan resistance
- dna sequence
- Encodes Ser219 → Val point mutant of the TEV protease catalytic domain
- S219V mutant has been shown to be more stable and more efficient as a catalyst than the wild-type protease
- pETTev produces an MBP-His-TEV fusion protein with an internal cleavage site
- The product self-cleaves intracellularly to yield His-tagged protease, MW = 28.5 kDa
