Synthesis, Redox and Spectroscopic Properties of Pterin of Molybdenum Cofactors [PDF]
Molecules, 2022 Pterins are bicyclic heterocycles that are found widely across Nature and are involved in a variety of biological functions. Notably, pterins are found at the core of molybdenum cofactor (Moco) containing enzymes in the molybdopterin (MPT) ligand that ...

Excess molybdenum impairs growth, nitrogen metabolism and nutrient translocation of soybean in Bradyrhizobium symbiosis, with parallels to tungsten stress [PDF]
Frontiers in Plant ScienceMolybdenum (Mo) serves an important biological role as part of cofactors of various enzymes in all domains of life. In plants, it is critical for nitrogen metabolism and integral to rhizobial enzymes such as nitrogenase, which is essential for plant ...

The pterin molybdenum cofactors.
Journal of Biological Chemistry, 1992 crassa, demonstrated that the inactive apoprotein of nitrate reductase in extracts of the mutant could be reconstituted by the addition of denatured preparations of purified molybdoenzymes from animal, fungal, or bacterial origin. This crucial finding showed that mol- ybdoenzymes contain a dissociable entity fitting the description of a cofactor and ...

The Influence of Micronutrient Trace Metals on Microcystis aeruginosa Growth and Toxin Production
Toxins, 2022 Microcystis aeruginosa is a widespread cyanobacteria capable of producing hepatotoxic microcystins. Understanding the environmental factors that influence its growth and toxin production is essential to managing the negative effects on freshwater systems.

Structural basis of thermal stability of the tungsten cofactor synthesis protein MoaB from Pyrococcus furiosus. [PDF]
PLoS ONE, 2014 Molybdenum and tungsten cofactors share a similar pterin-based scaffold, which hosts an ene-dithiolate function being essential for the coordination of either molybdenum or tungsten.
