A team of researchers led by PNNL computational scientist Simone Raugei have revealed new insights about how this complex enzyme does its job, finding that the seemingly wasteful formation of hydrogen ...

Through the biological fixation of the element nitrogen by the enzyme nitrogenase, organisms gain access to molecular nitrogen (N2) in the Earth's atmosphere, which is essential for building cellular ...

In an effort to better understand nitrogenase—the essential biocatalyst that bacteria use to convert N 2 into ammonia—researchers have now solved a mystery concerning the origins of a carbide ion in ...

In nature, enzymes known as nitrogenases convert N 2 found in the environment into a form that can be used to make amino acids and other biologically valuable nitrogen compounds. A multidisciplinary ...

Plants need nitrogen to grow, which they derive from 'fixed'or chemically available nitrogen in the soil. How the nitrogen is extracted happens through a process called biological nitrogen fixation.

Nitrogen is an essential component in the production of amino acids and nucleic acids - both necessary for cell growth and function. Although the atmosphere is composed of nearly 80% nitrogen, this ...
