蛋白酶S
英文名稱:Protease S Aureus;Endoproteinase Glu-C from Staphylococcus aureus V8;V8 Protease
其他名稱:V8蛋白酶S
CAS號:66676-43-5
級別:BR
來源:Staph aureus V8
Activity:≥500units/mg
活力定義:One Unit causes a change of 0.001 A280 nm per minute at 37℃, pH 7.8 usingcasein as the substrate
產(chǎn)品描述:Protease S. aureus V8 (Endoproteinase-Glu-C) specificallycleaves peptide bonds on the COOH-terminal side of either aspartic or glutamicacids. In the presence of ammonium, the enzyme specificity is limited toglutamic sites. It has a molecular weight of 27,000 daltons and optimum pH's of4.0 and 7.8 with hemoglobin as the substrate. Protease S. aureus V8 isinhibited by diisopropylfluorophosphate and monovalent anions such as F-, Cl-,CH3COO- and NO3. Enzyme activity is determined by the casein digestion assaydescribed by Drapeau (Methods Enzymol., 45, 469, 1976).
