Previously, it has been impossible to capture the high-resolution images of nitrogenase, the only enzyme capable of reducing nitrogen into ammonia, during catalytic action. Now, for the first time, ...

"If we can understand the mechanism of nitrogenase, we may not only figure out why nature evolved it to be such a complex enzyme, but we might also uncover design principles for ammonia production in ...

Heterocyst differentiation constitutes a pivotal developmental process in filamentous cyanobacteria, allowing these organisms to sidestep the oxygen sensitivity of the nitrogenase enzyme. Under ...

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 ...

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.
