Exonuclease I

Footprinting with Exonuclease III

but also because of an increase in the available probes that can be chosen in order to tackle a specific problem. There are two major groups of probes-the chemical probes and the enzymatic probes. These enzymatic probes, such as DNase I or exonuclease III, have the advantage

核酸外切酶 exonuclease

　　在核酸水解酶中，是具有从分子链的末端顺次水解磷酸二酯键而生成单核苷酸作用的酶，与核酸内切酶相对应。可大致分为水解磷酸二酯键的 3′端生成 5′ -单核苷酸的酶，及水解 5′端生成 3′ -单核苷酸的酶。前者有蛇毒磷酸二酯酶及大肠杆菌核酸外切酶Ⅰ、Ⅱ和Ⅲ等；后者有脾脏磷酸二酯酶、嗜酸乳杆菌（ Lac-tobacillus acidophilus）核酸酶。这些酶中还可以区别出从分子链的 3′末端或 5′末端开始切断和对单链 DNA或双链 DNA具有特异作用的酶。可利用这些酶水解
