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。

Molecular evolutionary analyses of mammalian ribonucleases have shown that gene duplication events giving three paralogous genes occurred in ruminant ancestors. The enzymes of the bovine species encoded by these genes, isolated from pancreas, brain and seminal vesicles, present similar enzymological

A surprising complexity of ubiquitin signaling has emerged with identification of different ubiquitin chain topologies. However, mechanisms of how the diverse ubiquitin codes control biological processes remain poorly understood. Here, we use quantitative whole-proteome mass spectrometry to identify yeast proteins
