Abstract
The enzymic activity of ribonuclease A was measured in the presence of several surfactants at pH7.2. Cationic surfactants with trimethylammonium and pyridinium head groups do not deactivate or denature the enzyme, whereas n-dodecylamine hydrochloride, like the anionic surfactant sodium n-dodecyl sulphate, deactivates and denatures ribonuclease A.
摘要
在pH7.2条件下，于几种表面活性剂存在的情况下测定了核糖核酸酶A的酶活性。带有三甲基铵和吡啶鎓头部基团的阳离子表面活性剂不会使该酶失活或变性，而盐酸正十二胺，与阴离子表面活性剂正十二烷基硫酸钠一样，会使核糖核酸酶A失活并变性。
