Assembly of nitrogenase FeMoco is one of the key processes in bioinorganic chemistry. NifB and NifEN are two essential elements immediately adjacent to each other along the biosynthetic pathway of ...

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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Nitrogen is an essential component of all living systems, playing important roles in everything from proteins and nucleic acids to vitamins. It is the most abundant element in Earth's atmosphere and ...

The FeMo cofactor is the catalytically active metal cluster in the enzyme nitrogenase that converts atmospheric dinitrogen into bioavailable ammonium. It is the largest and most complex metal site ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 74, No. 12 (Dec., 1977), pp. 5468-5471 (4 pages) A molybdenum cofactor (Mo-co) from xanthine oxidase ...
