Ribonuclease H

Evaluation of Retroviral Ribonuclease H Activity

Reverse transcription is the process whereby the single-stranded RNA genome of a retrovirus is converted into double-stranded DNA by the DNA polymerase and ribonuclease H (RNase H) activities of virus-coded reverse transcriptase (RT) (2 ,16

核糖核酸酶 H ribonuclease H

　　缩写为 RNase H。为分解与 DNA链形成双链的 RNA的核酸酶，从细菌到高等动物广泛存在。 RNA肿瘤病毒 的依赖 RNA的 DNA聚合酶，也具有核糖核酸酶 H的活性。细胞中的 RNase H，一般为核酸内切酶，而 Retro病毒粒子的 RNase，为核酸外切酶。都是将 RNA分解为在 5′端有磷酸基的低〔聚〕核苷酸或单核苷酸。 RNase H参与大肠杆菌素 E1质粒等 DNA复制的起始过程。  

Assay for Evaluating Ribonuclease H-Mediated Degradation of RNA-Antisense Oligonucleotide Duplexes

Ribonucleases H are complex enzymes whose functions are not clearly understood, further compounded by the fact that multiple forms of the enzyme are present in various organisms. They are known to recognize and degrade the ribonucleic acid (RNA
