Enteropeptidase, EC 3.4.21.9, Enterokinase, Serine protease 7, ENTK, MGC133046.
Enterokinase (rEK) Bovine Recombinant is the catalytic subunit of bovine enterokinase, which is expressed by the yeast and purified to yield a high enzyme activity preparation. EK recognizes the sequence Asp-Asp-Asp-Asp-Lys and cleaves the peptide bond after the lysine residue. The enzyme can be used to cleave any fusion protein that carries this sequence.
Pichia pastoris
Liquid solution.
EK in 50mM potassium phosphate, pH 8.0, 500mM NaCl and 50% glycerol should be stored at -20°C.
One year when stored at –20°C, three weeks at room temperature. Please avoid freeze-thaw cycles.
One unit of EK is the amount of enzyme required to digest 0.5mg of thioredoxin-NP-27 fusion protein to 90% completion in 16 hours at 37oC.
