DNase enzymes can be inhaled using a nebulizer by cystic fibrosis sufferers. DNase enzymes help because white blood cells accumulate in the mucus, and, when they break down, they release DNA, which adds to the 'stickiness' of the mucus. DNase enzymes break down the DNA, and the mucus is much easier to clear from the lungs.
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 producing tetranucleotides.
Structure of RNase A. EC 3.1.27.5: RNase A is an RNase that is commonly used in research. RNase A (e.g., bovine pancreatic ribonuclease A: ) is one of the hardiest enzymes in common laboratory usage; one method of isolating it is to boil a crude cellular extract until all enzymes other than RNase A are denatured. It is specific for single ...
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.

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 DNase footprinting assay [1] is a DNA footprinting technique from molecular biology/biochemistry that detects DNA-protein interaction using the fact that a protein bound to DNA will often protect that DNA from enzymatic cleavage. This makes it possible to locate a protein binding site on a particular DNA molecule.
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.
