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]
DNase I contains four ion-binding pockets, and requires Ca 2+ and Mg 2+ for hydrolyzing double-stranded DNA. [5] Two of the sites strongly bind Ca 2+ while the other two coordinate Mg 2+ . Little has been published on the number and location of the Mg 2+ binding sites, although it has been proposed that Mg 2+ is located near the catalytic ...
Ribonuclease (commonly abbreviated RNase) is a type of nuclease that catalyzes the degradation of RNA into smaller components. Ribonucleases can be divided into endoribonucleases and exoribonucleases, and comprise several sub-classes within the EC 2.7 (for the phosphorolytic enzymes) and 3.1 (for the hydrolytic enzymes) classes of enzymes.
Intentional breaks are generated as intermediaries in meiosis and V(D)J recombination, which are primarily repaired through homologous recombination and non-homologous end joining. Both cases require the ends in double strand breaks be processed by nucleases before repair can take place. One such nuclease is Mre11 complexed with Rad50.
During meiosis, homologous recombination can produce new combinations of genes as shown here between similar but not identical copies of human chromosome 1. Homologous recombination is a type of genetic recombination in which genetic information is exchanged between two similar or identical molecules of double-stranded or single-stranded ...
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.
There are some questions that need answers around the league. From Adam Silver's trial balloon, to All-Star omissions that don't truly feel like snubs, to Bronny James bringing out all the extreme ...
