Defining the role of aerobic respiration in the metabolism and bioenergetics of Enterococcus faecalis
This study demonstrates that in *Enterococcus faecalis*, the cytosolic NADH oxidase (Nox) is the primary consumer of oxygen and a key regulator of redox and energy homeostasis, while the F-type ATP synthase serves as the major generator of proton motive force, with the electron transport chain and Nox playing complementary roles in the bacterium's aerobic bioenergetics.
