WebEC 3.1.26.4: RNase H is a ribonuclease that cleaves the RNA in a DNA/RNA duplex to produce ssDNA. RNase H is a non-specific endonuclease and catalyzes the cleavage of RNA via a hydrolytic mechanism, aided by an enzyme-bound divalent metal ion. RNase H leaves a 5'-phosphorylated product. [7] The role of the DNase enzyme in cells includes breaking down extracellular DNA(ecDNA) excreted by apoptosis, necrosis, and neutrophil extracellular traps(NET) of cells to help reduce inflammatory responses that otherwise are elicited. See more Deoxyribonuclease (DNase, for short) refers to a group of glycoprotein endonucleases which are enzymes that catalyze the hydrolytic cleavage of phosphodiester linkages in the DNA backbone, thus … See more The two main types of DNase found in metazoans are known as deoxyribonuclease I (DNase I) and deoxyribonuclease II (DNase II). These two families have subcategories within them. The DNase I Family: DNase I, DNase1L1, DNase 1L2, DNase1L3 See more Laboratory applications DNase is commonly used when purifying proteins that are extracted from prokaryotic organisms.

This type of exonuclease is known as exodeoxyribonucleases. Others cleave anywhere along the chain, known as endodeoxyribonucleases (a subset of endonucleases.) … See more DNA absorbs ultraviolet (UV) light with a wavelength of maximal absorbance near 260 nm. This absorption is due to the pi electrons in the aromatic bases of the DNA.
