The NagY regulator: A member of the BglG/SacY antiterminator family conserved in and involved in virulence.

is a commensal bacterium of the gastrointestinal tract but also a major nosocomial pathogen. This bacterium uses regulators like BglG/SacY family of transcriptional antiterminators to adapt its metabolism during host colonization. In this report, we investigated the role of the BglG/SacY family antiterminator NagY in the regulation of the operon in presence of N-acetylglucosamine, with encoding a transporter of this carbohydrate, as well as the expression of the virulence factor HylA.
