A proteinase,which has important work on turbot digestive,was purified from turbot(Scophthalmus maximus L.) and its major physical and chemical characteristics were studied and reported in this article.The intestine proteinase extraction was prepared through homogenate and centrifugation by Tris-HCl buffer at low temperature.The supernatant was purified through ammonium sulfate grading precipitation further and the active component was dialyzed and concentrated.Then the condensed proteinase was purified by means of DEAE-Sepharose Fast Flow anion-exchange chromatography with an elution of a linear gradient of 5 mmol·L~(-1) Tris-HCl buffer(pH 8.5) containing 1.0 mol·L~(-1) NaCl.At last,the pure enzyme was obtained through Sephadex G-100 chromatography with an elution of 5mmol·L~(1) TrisHCl buffer(pH 8.5).The purity of the purified intestine proteinase was confirmed by the presence of a single band on SDS-PAGE.The relative molecular mass of this enzyme was determined to be about 58 kD.By using casein as substrate to measure proteinase activity,the characterization of turbot intestine proteinase was made.The enzyme is stable at pH 6.0-11.0 and temperature below 30 ℃.When the temperature rose,there was a rapid decline of its stability.The enzyme showed maximum activity at pH 9.0 and 50 ℃.When the temperature declined,the optimum pH of enzyme showed a trend of moving to alkaline.And when the action time prolonged,the optimum temperature of enzyme showed a trend to decline.Furthermore,the enzyme is activated by Mn~(2+) and inactivated by Cu~(2+),Zn~(2+),Ag~+,Fe~(3+).In further studies,it was inhibited by SH-enzyme inhibitors such as p-Hydroxymercuribenzoate(PCMB) and N-bromosuccinimide(NBS) remarkably,and partially inhibited by tosyl-lysine chloromethyl ketone(TLCK).Using casein as the substrate, the Km value of enzyme is 2.92 g·L~(-1) at pH 9.0,50 ℃.The result showed the enzyme seemed to be a SH-enzyme. 以大菱鲆肠道为材料,对大菱鲆消化生理中起重要作用的肠蛋白酶的分离纯化条件和理化性质进行了研究。经Tris-HCl缓冲液抽提,硫酸铵分级分离,DEAE-Sepharose Fast Flow离子交换层析、Sephadex G-100凝胶过滤层析分离纯化,获得大菱鲆肠蛋白酶Ⅰ的电泳纯制品,并对该酶的性质进行了研究。结果显示:纯酶的分子量约为58kD。纯酶最适反应pH为9.0,最适反应温度50℃;pH稳定范围6.0~11.0,30℃以下酶活性稳定;Mn2+可激活大菱鲆肠蛋白酶Ⅰ,Cu2+、Zn2+、Ag+、Fe3+则对酶活性有抑制作用;巯基蛋白酶抑制剂显著抑制大菱鲆肠蛋白酶Ⅰ的活性,金属蛋白酶抑制剂对大菱鲆肠蛋白酶Ⅰ无影响。50℃、pH9.0条件下以双倒数作图法得大菱鲆肠蛋白酶Ⅰ催化酪蛋白水解的Km值为2.92g.L-1。   << 更多相关文摘      相关查询 tris— tris ( tris tris－hcl tris- tris diluent tris imidazole Tris碱 tris (3 tris (5 tris (2 tris base
