应用
该酶已用于一项检测不受Benzonase核酸酶降解的Tf1 RNA量的检测中。粟酒裂殖酵母的Tf1元件是含有长末端重复序列的反转录转座子，可编码功能性蛋白酶、逆转录酶和整合酶蛋白。它还用于从细胞裂解物中获得的核颗粒和核提取物的分馏。
超纯的Benzonase核酸酶，或来自粘质沙雷氏菌的内切核酸酶，已用于一项评估十二烷基苯磺酸钠和消泡剂对粘质沙雷氏菌内切核酸酶活性影响的研究中。来自粘质沙雷氏菌的内切核酸酶已用于一项探究染色质亚基结构的研究中。
用于去除蛋白样品中的核酸。
生化/生理作用
Benzonase®是一种来自粘质沙雷氏菌的基因工程改造内切核酸酶。该蛋白质是30kDa亚基的二聚体，带有两个必需的二硫键。该内切核酸酶可攻击并降解所有形式的DNA和RNA（单链的、双链的、线性的和环化的），并可在一系列宽泛的操作条件下具有高效性。它可将核酸完全消化为长度为3至5个碱基的5′-单磷酸末端寡核苷酸。这是从重组蛋白中去除核酸的理想选择。它还可用于需要完全消化核酸的应用。它还可降低蛋白提取物的粘度并防止细胞成团。用这种酶对蛋白样品进行预处理可通过去除任何结合的核酸而提高它在2D凝胶电泳中的分辨率。最适的酶活pH为8.0-9.2。
消化天然或热变性的DNA和RNA。
单位定义
在pH 8.0，37 °C条件下，一个单位的酶在30分钟内可将超声的鲑鱼精子DNA消化成等同于1.0 ΔA260的酸可溶寡核苷酸（2.625 ml反应体积）。
外形
在含有20 mM Tris HCl, pH 8.0, 2 mM MgCl2及20 mM NaCl的50%甘油中的溶液。
