Pichia Pastoris Source Kex2 Recombinant Protease (Animal Origin Free)
Kex 2 protease
Enzyme Commission Number: EC 3.4.21.61
Gene Aliases:
Kexin; YSCF; Kex-2
Digestion Conditions:
Stable pH range: 5.0~6.0
Optimum catalytic pH: 9.0
Optimum catalytic temperature: 37℃
Scientific Background: Yeast KEX2 is a calcium-dependent serine protease that shares structural similarities with the bacterial protease subtilisin. KEX2 hydrolyzes the bond between Lys-Arg, Arg-Arg, Pro-Arg amino acid pairs. Recombinant KEX2 is useful for processing fusion proteins that contain the KEX2 recognition site. The enzyme stabilizes in a pH range of 5.0-6.0. The optimum catalytic pH is 9.0. The enzyme is not inhibited by conventional serine protease inhibitors such as PMSF, TPCK and TLCK.
Storage, Stability, and Shipping: Store product at –80°C for up to 1 year. Aliquot enzymes to avoid freeze / thaw cycles.
Storage Instructions
Recommended storage temperature:2℃-8℃.
Transport condition: blue ice to keep the environment cool.
It should be stored in 20mM NaAc-HAc (pH 5.0-5.5) and 2mM Ca2+.
