Is dna gyrase only in prokaryotes

WebMar 5, 2024 · DNA gyrase is a type of topoisomerase, found in bacteria and some archaea, that helps prevent the overwinding of DNA. (Some antibiotics kill bacteria by targeting DNA gyrase.) In addition, histone-like proteins bind DNA and aid in DNA packaging. WebIn prokaryotes, gyrase is an antibacterial target. [2] Indeed, these enzymes are of interest for a wide range of effects. Function [ edit] Type II topoisomerases increase or decrease the linking number of a DNA loop by 2 units, and it promotes chromosome disentanglement.
