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
