DNA gyrase
A topoisomerase that removes supercoils from DNA by first producing double-strand breaks and then sealing them.
DNA gyrase A topoisomerase that catalyzes the ATP-driven introduction of negative supercoils into DNA. Also called topoisomerase II.

DNA gyrase

Some bacteria do this by modifying their DNA gyrase.
Others, e.g., Mycobacterium tuberculosis, develop quinolone resistance by synthesizing a protein that resembles a short length of DNA.
Host DNA gyrase puts negative supercoils in the circular chromosome, causing A-T rich regions to unwind and drive transcription.
Transcription starts from the constitutive PL, PR and PR' promoters producing the 'immediate early' transcripts.
