Oldest enzyme in cellular respiration isolated

FRANKFURT. Researchers from Goethe University have found what is perhaps the oldest enzyme in cellular respiration. They have now been able to isolate an extremely fragile protein complex called “Rnf” from the heat-loving bacterium Thermotoga maritima. In fact, the genes that encode for the enzyme were already discovered around 10 years ago. However, the researchers from Frankfurt have now succeeded for the first time in isolating the enzyme and thus in proving that it really is formed by bacteria and used for cellular energy production.
