Hydrogen-Producing Enzymes Found in Archaea

Scientists from Monash University have discovered hydrogen-producing enzymes in archaea, a domain of life previously thought not to possess such enzymes. This finding challenges long-held beliefs and reveals that archaea have been producing and consuming hydrogen for two billion years, aiding their survival in extreme environments. The enzymes, known as hydrogenases, are smaller and more complex than those found in bacteria and eukarya and could improve hydrogen energy systems utilized by biotech firms. This research not only sheds light on the evolutionary history of eukaryotes but also offers potential advancements in green energy technology.
