Cryo-EM structure of the complete E. coli DNA gyrase nucleoprotein complex

Abstract

Bacterial DNA gyrase is the only type II DNA topoisomerase capable of introducing negative supercoils into DNA and is of interest as a drug target. Here the authors present the cryo-EM structure of the complete E. coli DNA gyrase bound to a 180 bp double-stranded DNA and the antibiotic gepotidacin, which reveals the connections between the functional domains and their spatial organization.
