| | Acid phosphatase from Branchiostoma beleheri was isolated and purified by ammonium sulfate fractionation,Sephadex G-75 gel filtration and CM-cellulose chromatography under acid condition. The purified enzyme exhibits absorption peaks at 280 nm and 500 nm, with a shoulder at 320 nm. Iron has been demonstrated in the prosthetic group of the enzyme by atomic absorption spec-troscopy and confirmed with O-phenanthroline colorimetry. Denaturation and inactivation rate constants of ACPase by Na2S2O4 has been deter... | | 从厦门文昌鱼Branchiostoma belcheri(Gray)分离提纯酸性磷酯酶(EC3.1,3.2),进一步经Sephadex G-75和羧甲基纤维素(CM-52)柱层析纯化,获得聚丙烯酰胺凝胶电泳单一纯酶制剂,比活力为351μm/min mg。酶液吸收峰在280nm,320nm,500nm,表现出含铁离子蛋白的特征吸收峰,用原子吸收法和化学法(邻啡绕啉比色法)分析,证明了文昌鱼酸性磷酸酯酶(ACPase)含有铁离子;还原剂Na_2S_2O_4处理浓度提高,酶活力及荧光强度下降,280nm和500nm峰下降,320nm峰消失,以Na_2S_2O_4测定ACPase失活和变性速度常激,结果表明,Na_2S_2O_4的失活常数大于变性带数。 | | 文摘来源 | |   |
