Sinorhizobium meliloti, a nitrogen-fixing bacterium, forms a symbiotic relationship with legumes in the root nodules of the plant. Because these bacteria must produce enzymes to modify environmental nitrogen, they are also able to detect levels of oxygen using the FixL-FixJ two-component system. More information about this system is available here: Oxygen-Sensing Histidine Protein Kinases.

The DosT/DevS system found in Mycobacterium tuberculosis has an analogous oxygen-sensing function. This article explains it in more detail DosT/DevS - Oxygen-Switched Kinases.
