一般描述
RNase A（核糖核酸酶A）是一种内切核糖核酸酶，在嘧啶核苷酸后裂解单链RNA的磷酸二酯键。它可切割3′磷酸基末端（例如，pG-pG-pC-pA-pG将切割为pG-pG-pCp 和A-pG）。对单链RNA表现出最高活性。RNase A是含有四个二硫键的单链多肽。它与RNase B不同，并非糖蛋白。核糖核酸酶不会水解DNA，因为DNA缺乏形成环状中间体所必需的2′-OH基团。RNase A还可以水解蛋白质样品中的RNA。RNase A可被His12和His119的烷基化抑制并被钾盐和钠盐活化。RNAse在重金属离子存在时受到抑制。此外，RNase也被DNA竞争性抑制。
核糖核酸酶不水解脱氧核糖核酸，因为脱氧核糖核酸缺乏对环状中间体的形成至关重要的2′-羟基。核糖核酸酶可以水解蛋白质样品中的核糖核酸。胰腺核糖核酸酶A在嘧啶（尿嘧啶或胞嘧啶）磷酸键的 3′-侧。
应用
- RNase A用于去除DNA质粒和基因组DNA制品和蛋白质样品中的RNA。
- RNase A还用于RNA序列分析和保护测定。
- RNase A已用作计算辅助药物设计的工具。
- RNase A为RNA序列分析提供支持。
- RNase A水解蛋白质样品中的RNA。
- RNase A为DNA纯化提供支持。
核糖核酸酶A可用于从DNA质粒制备物和蛋白质样品中除去RNA。核糖核酸酶A可用于RNA酶保护测定、去除非特异性结合的RNA、分析RNA序列、水解蛋白质样品中包含的RNA、以及DNA的纯化。来自牛胰腺的核糖核酸酶A已被用于评估人核糖核酸酶-1的杂合酶活性的研究中。 来自牛胰腺的核糖核酸酶A也已被用于研究阳离子交换蛋白置换色谱中基于颗粒的整体柱。
