Usage
Recommended reaction buffer: pH 7.0-9.0, 50 mM Tris-HCl, 2 mM Ca2+ or HEPES, 5 mM Ca2+. If it is not used immediately after dissolving, it is recommended to dissolve the powder with 20 mM (pH 5.2) NaAc-HAc and 2 mM Ca2+ buffer to make the final concentration is about 1-10 mg/mL, then make suitable packing as your requirement and store at -20 centigrade. Reaction was carried out, using pH 7.0-9.0, 50 mM Tris-HCl, 2 mM Ca2+ or HEPES, 5 mM Ca2+ buffer.
Note: The optimum reaction pH of the enzyme is pH 9.0 and the optimum stable pH is 5.0-6.0.
Note: The optimum reaction pH of the enzyme is pH 9.0 and the optimum stable pH is 5.0-6.0.
Unit Definition
One unit of Kex2 activity will release 1μmol 4-nitroaniline per minute in a reaction volume of 3.0 mL at pH 8.0 and 25 centigrade with Boc-QRR-pNA (Boc-Gln-Arg-Arg-pNA) as the substrate.
