aerobisiin
Aerobisiin is a proposed family of oxygen-responsive regulatory proteins found in some aerobic microorganisms. In theoretical and exploratory literature, the term describes proteins that sense intracellular oxygen levels and coordinate expression of components of the aerobic respiratory chain. In speculative models, aerobisiin serves as a conceptual example of how bacteria might regulate respiration under fluctuating oxygen conditions.
Typically, aerobisiin proteins are described as containing a sensor module capable of redox changes in response
Distribution and sequence diversity are described in environmental bacteria and some archaea, especially in ecosystems where
Applications of the concept include framing how cells balance energy generation with oxidative stress, and guiding
