Biochem/physiol Actions

核糖核酸酶A是一种内切核糖核酸酶，可在嘧啶核苷酸后切割单链RNA。它在3'磷酸基末端进行攻击。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。RNA酶还可以水解蛋白质样品中的RNA。RNase A可被His12和His119的烷基化所抑制并被钾盐和钠盐所活化。

Features and Benefits

我们高度稳定的核糖核酸酶A——RNase A，适合于RNA去除、RNA测序和DNA纯化。

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。

Molecular evolutionary analyses of mammalian ribonucleases have shown that gene duplication events giving three paralogous genes occurred in ruminant ancestors.

The poor outcome of pancreas ductal adenocarcinomas (PDAC) is frequently linked to therapy resistance. Modulated electro-hyperthermia (mEHT) generated by 13.56 MHz capacitive radiofrequency can induce direct tumor damage and promote chemo- and radiotherapy. Here, we tested the effect of mEHT
