Deoxyribonuclease II (DNase II) is also known as acid deoxyribonuclease because it has optimal activity in the low pH environment of lysosomes where it is typically found in higher eukaryotes. Some forms of recombinant DNase II display a high level of activity in low pH in the absence of divalent metal ions, similar to eukaryotic DNase II. [7]
Deoxyribonuclease I (usually called DNase I), is an endonuclease of the DNase family coded by the human gene DNASE1. [5] DNase I is a nuclease that cleaves DNA preferentially at phosphodiester linkages adjacent to a pyrimidine nucleotide , yielding 5'-phosphate-terminated polynucleotides with a free hydroxyl group on position 3', on average ...
Deoxyribonuclease II (EC 3.1.22.1, DNase II, pancreatic DNase II, deoxyribonucleate 3'-nucleotidohydrolase, pancreatic DNase II, acid deoxyribonuclease, acid DNase) is an endonuclease that hydrolyzes phosphodiester linkages of deoxyribonucleotide in native and denatured DNA, yielding products with 3'-phosphates and 5'-hydroxyl ends, which occurs as a result of single-strand cleaving mechanism. [1]
Type I site-specific deoxyribonuclease (EC 3.1.21.3, type I restriction enzyme, deoxyribonuclease (ATP- and S-adenosyl-L-methionine-dependent), restriction-modification system, deoxyribonuclease (adenosine triphosphate-hydrolyzing), adenosine triphosphate-dependent deoxyribonuclease, ATP-dependent DNase, type 1 site-specific deoxyribonuclease) is an enzyme.

A deoxyribonucleotide is a nucleotide that contains deoxyribose.They are the monomeric units of the informational biopolymer, deoxyribonucleic acid ().Each deoxyribonucleotide comprises three parts: a deoxyribose sugar (monosaccharide), a nitrogenous base, and one phosphoryl group. [1]
In molecular biology, endonucleases are enzymes that cleave the phosphodiester bond within a polynucleotide chain (namely DNA or RNA).Some, such as deoxyribonuclease I, cut DNA relatively nonspecifically (with regard to sequence), while many, typically called restriction endonucleases or restriction enzymes, cleave only at very specific nucleotide sequences.
Anti-Deoxyribonuclease B (anti-DNase B) titres are a quantitative measure of the presence of serologic antibodies obtained from patients suspected of having a recent group A (Beta-hemolytic) streptococcus bacteria infection, from Streptococcus pyogenes.
The enzyme complex is composed of three different subunits called RecB, RecC, and RecD and hence the complex is named RecBCD (Figure 1). Before the discovery of the recD gene, [4] the enzyme was known as “RecBC.”
