Electronic landscape of the P-cluster of nitrogenase as revealed through many-electron quantum wavefunctions [PDF]
, 2019 The electronic structure of the nitrogenase metal cofactors is central to nitrogen fixation. However, the P-cluster and iron molybdenum cofactor, each containing eight irons, have resisted detailed characterization of their electronic properties. Through

The key role of nitric oxide in hypoxia: hypoxic vasodilation and energy supply-demand matching [PDF]
, 2013 Significance: a mismatch between energy supply and demand induces tissue hypoxia with the potential to cause cell death and organ failure. Whenever arterial oxygen concentration is reduced, increases in blood flow - 'hypoxic vasodilation' - occur in an ...

Child Neurology: Molybdenum cofactor deficiency [PDF]
Neurology, 2015 Molybdenum cofactor deficiency (MoCD) is a rare inherited metabolic disorder characterized by neonatal onset intractable seizures, severe psychomotor retardation, dysmorphic facies, and dislocated ocular lenses.1 A characteristic biochemical profile permits early diagnosis.

The ins and outs of metal homeostasis by the root nodule actinobacterium Frankia [PDF]
, 2014 Background: Frankia are actinobacteria that form a symbiotic nitrogen-fixing association with actinorhizal plants, and play a significant role in actinorhizal plant colonization of metal contaminated areas.

Metalloprotein Crystallography: More than a Structure [PDF]
, 2015 Metal ions and metallocofactors play important roles in a broad range of biochemical reactions. Accordingly, it has been estimated that as much as 25–50% of the proteome uses transition metal ions to carry out a variety of essential functions.

Trace elements induce predominance among methanogenic activity in anaerobic digestion
Frontiers in Microbiology, 2016 Trace elements play an essential role in all organisms due to their functions in enzyme complexes. In anaerobic digesters, control and supplementation of trace elements lead to stable and more efficient methane production processes while trace element ...

Catalytic conversion of nitrogen to ammonia by an iron model complex [PDF]
, 2013 The reduction of nitrogen (N_2) to ammonia (NH_3) is a requisite transformation for life. Although it is widely appreciated that the iron-rich cofactors of nitrogenase enzymes facilitate this transformation, how they do so remains poorly understood.

NifA is the master regulator of both nitrogenase systems in Rhodobacter capsulatus
MicrobiologyOpen, 2019 Rhodobacter capsulatus fixes atmospheric nitrogen (N2) by a molybdenum (Mo)‐nitrogenase and a Mo‐free iron (Fe)‐nitrogenase, whose production is induced or repressed by Mo, respectively. At low nanomolar Mo concentrations, both isoenzymes are synthesized

Molybdenum limitation of microbial nitrogen assimilation in aquatic ecosystems and pure cultures
Frontiers in Microbiology, 2012 Molybdenum (Mo) is an essential micronutrient for biological assimilation of nitrogen gas and nitrate because it is present in the cofactors of nitrogenase and nitrate reductase enzymes.
