DNA gyrase is an enzyme with two protein subunits; DNA topology is investigated that involves two types of DNA coiling; GyrA and GyrB that catalyzes (−) supercoiling at the expense of ATP hydrolysis; RNA polymerase (RNAP); gamma delta (γδ) resolvase is a site-specific recombinase from the γδ transposon the that utilizes (−) supercoils to delete a DNA sequence that is flanked by 100 bp Res sites; gyrase processivity refers to the number of reaction cycles one enzyme carries out in a single DNA binding event; the E. coli and Salmonella condensin is a multi-protein complex composed of three proteins, MukB, MukE, and MukF that compacts chromosomal DNA; the GyrA C-terminal domain (CTD) includes a long DNA binding section that has 6 pinwheel elements plus a short 3538 amino acid terminus called the tail; the Q10 rule states that reaction rates double for every 10° C increase in temperature; the first type is right-handed coils that Watson/Crick DNA strands adopt by winding around each other every 10.6 base pairs, the second type involves coiling of the double strands around each other in either a left handed (−) or right handed (+) direction
