Type II topoisomerases increase or decrease the linking number of a DNA loop by 2 units, and it promotes chromosome disentanglement. For example, DNA gyrase, a type II topoisomerase observed in E. coli and most other prokaryotes, introduces negative supercoils and decreases the linking number by 2. … See more Type II topoisomerases are topoisomerases that cut both strands of the DNA helix simultaneously in order to manage DNA tangles and supercoils. They use the hydrolysis of ATP, unlike Type I topoisomerase. … See more There are two subclasses of type II topoisomerases, type IIA and IIB. • Type IIA topoisomerases include the enzymes DNA gyrase, eukaryotic topoisomerase II (topo II), and bacterial topoisomerase IV (topo IV). These enzymes span all … See more Strand passage Type IIA topoisomerase operates through a "two-gate" mechanism (though this is a historical notation), a mechanism supported by biochemistry as well as by structural work. A strand of DNA, … See more Small molecules that target type II topoisomerase are divided into two classes: inhibitors and poisons. Due to their frequent presence in proliferating eukaryotic cells, inhibitors of type II topoisomerases have been extensively studied and used … See more Type IIA topoisomerases are essential in the separation of entangled daughter strands during replication. This function is believed to be … See more Type IIA Type IIA topoisomerases consist of several key motifs: • an N-terminal GHKL ATPase domain (for gyrase, Hsp, kinase and MutL), • a Toprim domain (a Rossmann fold subclass), which exists in both type … See more Catenation is the process by which two circular DNA strands are linked together like chain links. This occurs after DNA replication, where … See more WebTopoizomeraza zdolny do powodowania zarówno pojedynczych, jak i podwójnych pęknięć nici DNA w procesie zmiany "superzwiniętej" (ang. supercoiled) struktury DNA na formę zwiniętą, szczególnie w okolicy otwartych widełek replikacyjnych. ligaza DNA IV tworząca zespół z czynnikiem XRCC4, łączy dwa rozerwane zakończenia, port adelaide power song

DNK topoizomeraze (tip I: ЕЦ 5.99.1.2, tip II: ЕЦ 5.99.1.3) su enzimi koji odmotavaju i zamotavaju DNK, da bi DNK molekuli mogli da kontrolišu sintezu proteina. Topoizomeraze takođe olakšavaju DNK replikaciju. Neophodnost postojanja ovih enzima se zasniva na dvostruko heliksnom obliku molekula. [1] WebTopoizomeraza 2.
