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.
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+.
