Topoisomerase

Topoisomerase

Topoisomerases are enzymes that regulate the overwinding or underwinding of DNA.DNA's double-helical structure is entwined, which leads to the winding issue. Isomerization enzymes called topoisomerases work on DNA's topology. One strand of a DNA double helix is cut by type I topoisomerase, which is followed by relaxation and reannealing of the cut strand. Type I topoisomerases are divided into two subclasses: type IB topoisomerases, which employ a controlled rotary mechanism, and type IA topoisomerases, which share many structural and mechanistic features with the type II topoisomerases. One DNA double helix's two strands are cut by Type II topoisomerase, which then reanneals the cut strands after passing through another DNA double helix that hasn't been broken. Type IIA and type IIB topoisomerases, two subclasses of this class with related structures and mechanisms, are further divided.
