Descripción general
Kex2 is a Ca2+-dependent serine protease and cleaves at C-terminal site of Lys-Arg, Arg-Arg, Pro-Arg in pro-α,factor and killer-toxin precursors maturing, it was discovered in Saccharomyces cerevisiae.But Kex2 can’t recognize and cut a single basic amino acid,such as carboxyl end peptide bond of arginine and lysine. Recombinant Kex2 is a genetically engineered protein expressed in Pichia pastoris and purified by high pressure liquid chromatography. The optimal pH of Kex2 protease is 9.0, and the optimal temperature is 37 ℃. It is stable in buffer (pH 5.0-6.0). The activity of Kex2 is not affected by the conventional serine protease inhibitors such as PMSF, TPCK, TLCK inhibition. Kex2 Protease Recommended Method: Recommended reaction buffer: 5-10 mM Tris, 2mM Ca2+, pH 7.0-9.0 or HEPES, 5mM Ca2+, pH 7.0-9.0. If it is not used immediately after dissolution, it is recommended to use 20mM NaAc-HAc, 2mM Ca2+ (pH 5.0~5.5) buffer to dissolve the lyophilized powder. During the reaction, use 5-10 mM Tris, 2mM Ca2+, pH 7.0-9.0 or HEPES, 5mM Ca2+, pH 7.0-9.0 as the reaction diluent. Recommended conditions:
Catalytic activity: Cleavage of -Lys-Arg-|-Xaa- and -Arg-Arg-|-Xaa- bonds to process yeast alpha-factor pheromone and killer toxin precursors. Cofactor Ca2+. Note: Binds 3 Ca2+ ions per subunit.
Post-translational: O-glycosylated.
