The essential roles of metal ions in insect homeostasis and physiology [PDF]
, 2017 Metal ions play distinct roles in living organisms, including insects. Some, like sodium and potassium, are central players in osmoregulation and ‘blood and guts’ transport physiology, and have been implicated in cold adaptation.

Predicting compatibility between ferredoxins and the Fe protein of nitrogenase using in silico protein modeling. [PDF]
Protein SciAbstract Biological nitrogen fixation is the process by which certain bacteria and archaea use the enzyme nitrogenase to reduce atmospheric nitrogen into bioavailable ammonium. Engineering non‐nitrogen‐fixing organisms, like plants, to use nitrogenase could reduce dependency on synthetic fertilizer and mitigate the environmental impacts of industrial ...

Great metalloclusters in enzymology [PDF]
, 2002 Metallocluster-containing enzymes catalyze some of the most basic redox transformations in the biosphere. The reactions catalyzed by these enzymes typically involve small molecules such as N2, CO, and H2 that are used to generate both chemical building ...

Exogenous application of molybdenum affects the expression of CBF14 and the development of frost tolerance in wheat. [PDF]
, 2013 Wheat is able to cold acclimate in response to low temperatures and thereby increase its frost tolerance and the extent of this acclimation is greater in winter genotypes compared to spring genotypes.

Molybdenum cofactor deficiency [PDF]
, 2020 Molybdenum cofactor (MoCo) deficiency presents classically in the neonatal period, with convulsions intractable to anticonvulsant therapy and coma. The clinical manifestations of MoCo deficiency relating to the nervous system are generally considered to be functions of the deficiency of sulfite oxidase.

Molybdenum Cofactor Deficiency in Humans
Molecules, 2022 Molybdenum cofactor (Moco) deficiency (MoCD) is characterized by neonatal-onset myoclonic epileptic encephalopathy and dystonia with cerebral MRI changes similar to hypoxic–ischemic lesions. The molecular cause of the disease is the loss of sulfite oxidase (SOX) activity, one of four Moco-dependent enzymes in men.

Thiosulfoxide (Sulfane) Sulfur: New Chemistry and New Regulatory Roles in Biology
Molecules, 2014 The understanding of sulfur bonding is undergoing change. Old theories on hypervalency of sulfur and the nature of the chalcogen-chalcogen bond are now questioned.

Protein-bound molybdenum cofactor is bioavailable and rescues molybdenum cofactor-deficient C. elegans [PDF]
Genes & Development, 2020 The molybdenum cofactor (Moco) is a 520-Da prosthetic group that is synthesized in all domains of life. In animals, four oxidases (among them sulfite oxidase) use Moco as a prosthetic group. Moco is essential in animals; humans with mutations in genes that encode Moco biosynthetic enzymes display lethal neurological and ...

Nitrogenase: A nucleotide-dependent molecular switch [PDF]
, 1994 In the simplest terms, the biological nitrogen cycle is the reduction of atmospheric dinitrogen (N2) to ammonia with the subsequent reoxidation ammonia to dinitrogen (1).

The relationship between redox enzyme activity and electrochemical potential—cellular and mechanistic implications from protein film electrochemistry [PDF]
, 2011 In protein film electrochemistry a redox protein of interest is studied as an electroactive film adsorbed on an electrode surface. For redox enzymes this configuration allows quantification of the relationship between catalytic activity and ...
