ATP-dependent topoisomerase

ATP-dependent topoisomerase is an enzyme that helps manage the structure of DNA by relieving tangles and supercoils during cellular processes like replication and transcription. It uses energy from ATP molecules to cut one or both strands of the DNA, allow it to unwind or untangle, and then rejoin the strands safely. This activity ensures that DNA remains properly organized, which is essential for accurate copying and reading of genetic information. By consuming ATP, the enzyme can efficiently perform its functions, especially under conditions that demand active and controlled DNA topology management.
