Human activity redistributes nitrogen fixation across the terrestrial biosphere

All known life forms require nitrogen. However, more than 70% of all nitrogen on Earth occurs as inert, triple-bonded dinitrogen gas in the atmosphere, which is generally biologically unavailable. A ...

Protein protects biological nitrogen fixation from oxidative stress

A research team has discovered how the 'Shethna protein II' protects the nitrogen-fixing enzyme nitrogenase from damage. The oxygen sensor protein could help to make nitrogenase usable in ...

Inland, coastal regions have an overlooked role in nitrogen fixation

A new evaluation of biological nitrogen fixation for inland and coastal waters concludes that these habitats are an overlooked but important source of fixation globally. Robinson Fulweiler and ...
