Recombinant Bovine Enterokinase (rb-EK)

Recombinant Bovine Enterokinase (rb-EK)
General description
Enterokinase (rb-EK) 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.
