Crystal Structure of the Escherichia coli SbmC protein (AKA Gyrase Inhibitory Protein GyrI, AKA YeeB)

Structural highlights
FunctionSBMC_ECOLI Inhibits the supercoiling activity of DNA gyrase. Acts by inhibiting DNA gyrase at an early step, prior to (or at the step of) binding of DNA by the gyrase. It protects cells against toxins that target DNA gyrase, by inhibiting activity of these toxins and reducing the formation of lethal double-strand breaks in the cell. Protects cells against the natural plasmid-encoded toxins microcin B17 (MccB17) and CcdB, and synthetic quinolones. Can also protect cells against alkylating agents that act independently of DNA gyrase, suggesting a more general role in protecting cells against DNA damage.[1] [2] [3] [4] Evolutionary Conservation![]() Check, as determined by ConSurfDB.
