DNA gyrase, often referred to simply as gyrase, is an enzyme that relieves strain while double-strand DNA is being unwound by helicase. It is also known as DNA topoisomerase II. This causes negative supercoiling of the DNA. Bacterial DNA gyrase is the target of many antibiotics, including nalidixic acid, novobiocin, and ciprofloxacin.
Effect of ph and [H.sub.2][O.sub.2] dosage on the photooxidative degradation of Reactive Red 120 (RR120) by UV-[H.sub.2][O.sub.2] To monitor for antibiotic aftereffects, Collins and his colleagues set a flashy bait in bacterial cells--a molecule that glows when cut by hydroxyl radicals.
