Nitrogen Fixation and Hydrogen Evolution by Sterically Encumbered Mo-Nitrogenase

The substrate-reducing proteins of all nitrogenases (MoFe, VFe, and FeFe) are organized as alpha 2ss2(gamma 2) multimers with two functional halves. While their dimeric organization could afford improved structural stability of nitrogenases in vivo, previo ...

The Mononuclear Metal-Binding Site of Mo-Nitrogenase Is Not Required for Activity

Wenyu Gu

The biological N-2-fixation process is catalyzed exclusively by metallocofactor-containing nitrogenases. Structural and spectroscopic studies highlighted the presence of an additional mononuclear metal-binding (MMB) site, which can coordinate Fe in additio ...

Eutrophication (i.e. the increase of [in-]organic nutrients) may affect the functioning of coral reefs, but knowledge about the effects on nitrogen (N) cycling and its relationship to productivity within benthic reef communities is scarce. Thus, we investi ...

Species-specific effects of polyploidisation and plant traits of Centaurea maculosa and Senecio inaequidens on rhizosphere microorganisms

Alexandre Buttler, Edward Mitchell, Aurélie Thébault

Invasive plant species represent a threat to terrestrial ecosystems, but their effects on the soil biota and the mechanisms involved are not yet well understood. Many invasive species have undergone polyploidisation, leading to the coexistence of various c ...
