DNA topoisomerases, type II, are a class of enzymes that play a crucial role in regulating DNA topology during various cellular processes, such as DNA replication, transcription, and recombination. These enzymes are responsible for relaxing or tightening the supercoiled structure of DNA, which is essential for maintaining the proper function of the genome. Type II topoisomerases are divided into two subclasses: type IIA and type IIB. Type IIA topoisomerases, also known as topoisomerase II, are involved in DNA replication and transcription, and are often targeted by anti-cancer drugs. Type IIB topoisomerases, on the other hand, are involved in DNA repair and recombination. Type II topoisomerases work by creating temporary breaks in the DNA double helix, allowing the DNA strands to pass through each other and relieve tension. Once the topoisomerase has completed its task, it seals the DNA break, restoring the original topology of the DNA. In the medical field, type II topoisomerases are often targeted by drugs, such as etoposide and doxorubicin, which are used to treat various types of cancer. These drugs work by inhibiting the activity of type II topoisomerases, leading to the accumulation of DNA damage and ultimately causing cell death. However, the use of these drugs can also lead to side effects, such as nausea, vomiting, and hair loss.
