That process supports the food needs for more than 40 percent of the human population According to Dr. Edwin Antony, assistant professor of biological sciences at Marquette, the industrial nitrogen breakdown— called the HaberBosh process — uses a vast amount of energy, usually from fossil fuels. If scientists can engineer the ammoniaproducing enzyme from bacteria called nitrogenase for industrialscale ammonia production, it would be a tremendous achievement in agriculture and food production, he said Antony explained the process: Nature uses bacteria to turn air’s molecular nitrogen into ammonia. This is achieved using an enzyme called nitrogenase, which is made up of two identical halves and uses the energy from adenosine triphosphate (ATP) to break down the triple bond of dinitrogen to produce ammonia The Marquette biochemist and his collaborators found that the long held presumption that the two symmetrical halves worked independently to make ammonia was incorrect. Instead, the two sides cooperate, alternating through different steps to make efficient use of the complex enzyme.

Since the sides are symmetrical, moving one side up forces the other side to move down, positioning different parts of the machine for different chemical reactions Plenty of Horne: Future of Declares by Michael Horne the Harbor District by Michael Horne Other researchers were from Utah State University, Northwestern University, Virginia Tech University and the Pacific Northwestern National Laboratory You Might Also Like Urban Milwaukee 11,757 likes Like Page Sign Up Be the first of your friends to like this http://urbanmilwaukee.com/pressrelease/marquettebiochemistidentifiesblueprintforenzymethatmakesammonia/ 3/7 11/4/2016 Marquette biochemist identifies blueprint for enzyme that makes ammonia » Urban Milwaukee UrbanMilwaukee.com Warning: Don't Diet Before You See Friday Photos: DoMUS Rising Court Watch: Secrecy and the John Expansion This Doe Probe Building the best local news and data source in Milwaukee $31,460USD InDemand Recent Comments PMD on Mayor Barrett Reports on InPerson Absentee Voting Secret Trick to an Incredible Shave Get Free Avocado Mayo Delivered to Free Jar of Gourmet Almond Butter – Numbers Your Door No Strings Attached Press Releases by Marquette University Jason on Mayor Barrett Reports on InPerson Absentee Voting Numbers Jason on More Than Downtown Development Needed PMD on Murphy’s Law: Schimel Patrols Only Democratic Voters?
