Nitrogenases are enzymes (EC 1.18.6.1 EC 1.19.6.1) that are produced by certain bacteria, such as cyanobacteria (blue-green bacteria) and rhizobacteria. These enzymes are responsible for …

But the lion's share of usable nitrogen is created by bacteria, using the enzyme nitrogenase. Nitrogen-fixing bacteria have the ability to convert nitrogen gas into ammonia, which is easily …

Nitrogenase is defined as a metalloenzyme that catalyzes the reduction of nitrogen gas (N2) to ammonia (NH3), utilizing a complex FeMo cofactor known as the M-cluster.

Jan 27, 2014 · In 1934, Burk coined the term “nitrogenase” (10, 11) for the enzyme that catalyzes the conversion of N 2 to a bioaccessible form of nitrogen, and initiated the first meaningful …

May 30, 2025 · The architecture of the active site and its surrounds that promote the chemical choreography of nitrogenase in its performance space are outlined, and key features and …

Jan 28, 2025 · What is Nitrogenase? Nitrogenase is an enzyme complex that catalyzes the chemical reaction converting atmospheric nitrogen (N₂) into ammonia (NH₃), a process known …

The enzyme responsible for N 2 fixation is nitrogenase, which breaks the strong triple bond in N 2 to form ammonia (NH 3), thereby turning nitrogen into a bioavailable form which is then …

The ammonia-manufacturing center of the diazotroph is nitrogenase. The picture below is taken from an X-ray crystal structure of the enzyme (reference cited at the bottom of the page).

Jun 9, 2025 · Nitrogenase is a complex enzyme that plays a crucial role in the process of biological nitrogen fixation, converting atmospheric nitrogen (N2) into a form that can be used …

Jul 22, 2025 · Explore the molecular workings of nitrogenase, the enzyme that converts atmospheric nitrogen and serves as a cornerstone for the global nitrogen cycle.
