More than half of the protein within our body can be directly traced to a process invented more than 100 years ago by two ...

The biological route to fixing nitrogen is done by diazotrophs, nitrogen-fixing bacteria that contain an enzyme called nitrogenase. In contrast to the Haber-Bosch process, nitrogenase can be ...

In nature, nitrogen is reduced by nitrogenase enzymes, which contain large metalloproteins and promote a sequence of proton-coupled electron-transfer reactions to accomplish the reduction.

This metallic ion appears to serve as an essential ion cofactor for the enzyme nitrogenase, which catalyzes the reduction of nitrogen to ammonia. Collect a bottle of soil culture (nitrogen-free medium ...

Instead, diverse prokaryotes use an enzyme called nitrogenase to catalyze biological nitrogen fixation (BNF), which converts the nitrogen into a biologically available form. Diazotrophs are a specific ...
