Summary of topoisomerase types and catalytic mechanisms. The topoisomerases are categorized based on whether they catalyze single- (type I) or double-stranded (type II) DNA breaks.

Feb 27, 2023 · What is Topoisomerase? Topoisomerase is an essential enzyme that aids in the DNA replication process, segregation of chromosomes, transcription, and also in recombination.

One of topoisomerase II’s most critical jobs comes just before a cell divides. After a cell copies its entire genome, the two identical sets of chromosomes (called sister chromatids) are tangled together.

Types of Topoisomerase Topoisomerases are enzymes classified into two main types based on their mechanisms of action and the number of strands they cleave during their catalytic cycle.

Topoisomerase I and II control the topological state of DNA so that it can undergo replication, transcription, repair, and chromosomal segregation (Liu, 1989; Osheroff, 1989).
