Description:
Enterokinase is a serine protease that can specifically cleave the sequence Asp-Asp-Asp-Asp-Lys after the lysine residue . It applies for digesting fusion proteins to release the fusion partner or tag from the target protein.
Native enterokinase is composed of a 115 kDa heavy chain as a membrane anchor and a 35 kDa light chain as the catalytic subunit. Recombinant bovine enterokinase is a specially prepared recombinant enzyme, consisting of the catalytic subunit of the holoenzyme. This subunit is expressed and purified from E.coli, yielding an enzyme with higher specific activity. This results in more
efficient cleavage using less enzyme.
 
Note:
1. Rb-EK is known to be inhibited by >2 M Urea, >250 mM NaCl, >20 mM β-ME, >0.1% SDS, or >50 mM imidazole. Dialyze your fusion protein to remove the inhibitors prior to digestion with rb-EK.
2. Avoid using phosphate buffer.
