Ancient enzyme discovery may aid carbon dioxide removal

phys.org

Researchers have discovered how an ancient enzyme involved in cellular respiration works, shedding light on a process that could help remove carbon dioxide from the environment. This enzyme, part of the Rnf complex, was previously difficult to isolate. The study reveals that when bacteria convert carbon dioxide and hydrogen into acetic acid, they also produce ATP by pumping sodium ions out of the cell. This process involves a dynamic interaction of proteins within the Rnf complex, which facilitates electron transfer. The findings suggest potential applications for reducing greenhouse gases and creating valuable materials in the chemical industry. Understanding this mechanism may also lead to new treatments for diseases linked to similar respiratory enzymes.
