General description
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。
Application
- 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。
