9.B.334.1.2 | Uncharacterized sensor histidine kinase of 434 aas and 6 TMSs with a COG0642 domain. | Archaea |
Candidatus Lokiarchaeota | UP of Lokiarchaeum sp. GC14-75 |

9.B.334.1.3 | The aerotaxis protein, Aer or YqjJ of 506 aas and 1 or 2 TMSs. The aerotactic response causes the accumulation of cells around air bubbles in liquid media under a cover slip. The nature of the sensory stimulus detected by this protein is the proton motive force (pmf) and the cellular redox state. It uses an FAD prosthetic group as a redox sensor to monitor oxygen levels (Bibikov et al. 1997). The redox properties and PAS domain structure of Aer indicate a multistate sensing mechanism (Maschmann et al. 2022). | Bacteria |
Pseudomonadota | Aer of E. coli |
