Regulation of energy metabolism by the extracytoplasmic function (ECF) σ factors of Arcobacter butzleri.

The extracytoplasmic function (ECF) σ factors are fundamental for bacterial adaptation to distinct environments and for survival under different stress conditions. The emerging pathogen Arcobacter butzleri possesses seven putative pairs of σ/anti-σ factors belonging to the ECF family. Here, we repor...
