Also catalyzes the interconversion of other topological isomers of dsDNA rings, including catenanes. Gyrase from M.tuberculosis has higher decatenation than supercoiling activity compared to E.coli; as M.tuberculosis only has 1 type II topoisomerase, gyrase has to fulfill the decatenation function of topoisomerase IV as well.

nuoGProbable NADH dehydrogenase I (chain G) NuoG (NADH-ubiquinone oxidoreductase chain G); NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be menaquinone.
