DESCRIPTION:
Recombinant Enterokinase (rEK) is the catalytic subunit of bovine enterokinase with a Cys112->Ala mutation. rEK is expressed and isolated from the yeast Saccharomyces Cerevisin to yield a highly purified enzyme preparation. rEK recognizes the identical cleavage site as the native enzyme (i.e. AspAspAspAspLys). rEK can be used to cleave any fusion protein containing the recognition sequence. With the free Cys112 mutated to Ala, rEK may have a better stability. The molecular weight of rEK is about 38kd due to glycosylation.


SOURCE:
Sarccharomyces Cerevisin Cells.

PURITY:
95% by SDS-PAGE.


ACTIVITY:
One unit is defined as the amount of enzyme needed to cleave 50 mg of fusion protien 16 hours at 25C in 50 mM Tris-HCl, 50 mM NaCl, 2mM CaCl2, pH7.5.

 

PRESENTATION:
Solution in 50 mM Tris-HCl, 0.2M NaCl, 20% Glycerol, pH7.0.

STORAGE:
Store at -20C.
