Pichia Pastoris Source Kex2 Recombinant Protease With Animal Origin Free
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.
