DNase I Structure: DNase I is a glycoprotein with a molecular weight of 30,000 Da and a carbohydrate chain of 8-10 residues attached to Asn18 (orange). [3] It is an 𝛼,𝛽-protein with two 6-stranded 𝛽-pleated sheets which form the core of the structure. [4] These two core sheets run parallel, and all others run antiparallel.
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.
DNase I and DNase1L1 (DNaseX) carry out programmed cell death (apoptosis) and thus protect the human body from the development of tumor cells. Conversely, the absence of DNase enzyme activity leads to the increased formation of tumor cells, as the execution of apoptosis is prevented. [10] [11]

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.

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.
