英文名称：Protease S Aureus
产品货号：Y13044
产品规格：1mg

CAS：66676-43-5
Activity：≥500units/mg
活力定义：One Unit causes a change of 0.001 A280nm per minute at 37℃,pH 7.8 using casein as the substrate
产品描述：Protease S.aureus V8 (Endoproteinase-Glu-C) specifically cleaves peptide bonds on the COOH-terminal side of either aspartic or glutamic acids.In the presence of ammonium,the enzyme specificity is limited to glutamic sites.It has a molecular weight of 27,000 daltons and optimum pH"s of 4.0 and 7.8 with hemoglobin as the substrate.Protease S.aureus V8 is inhibited by diisopropylfluorophosphate and monovalent anions such as F-,Cl-,CH3COO- and NO3.Enzyme activity is determined by the casein digestion assay described by Drapeau (Methods Enzymol.,45,469,1976).
