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。

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。
