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 ...

Pterin function in bacteria [PDF]
Pteridines, 2017 Pterins are widely conserved biomolecules that play essential roles in diverse organisms. First described as enzymatic cofactors in eukaryotic systems, bacterial pterins were discovered in cyanobacteria soon after.

A model to understand type I oxidations of biomolecules photosensitized by pterins
Journal of Photochemistry and Photobiology, 2021 Photosensitized oxidations, in part responsible for the harmful effect of UV and visible radiation on biological systems, can take place through type I (generation of radicals) and type II (singlet oxygen) mechanisms.

Tryptophan oxidation photosensitized by pterin
Free Radical Biology and Medicine, 2013 Pterins are normal components of cells and they have been previously identified as good photosensitizers under UV-A irradiation, inducing DNA damage and oxidation of nucleotides. In this work, we have investigated the ability of pterin (Ptr), the parent compound of oxidized pterins, to photosensitize the oxidation of another class of biomolecules ...

Journal of Biological Chemistry, 1959 Publisher Summary This chapter describes the bacterial pterin deaminase. In the standard assay, the mixture contains 0.05 ml of pterin carboxylic acid, 0.8 ml of phosphate buffer, and 0.02 to 0.15 ml of enzyme in a final volume of 1.0 ml. Incubation is carried out at 23° in a 1-ml Beckman quartz cuvette with a light path of 1.00 cm. Reaction is begun

Cells, 2019 Inborn errors of monoamine neurotransmitter biosynthesis and degradation belong to the rare inborn errors of metabolism. They are caused by monogenic variants in the genes encoding the proteins involved in (1) neurotransmitter biosynthesis (like tyrosine

Electron Transfer Initiated Reactions Photoinduced by Pterins
Pteridines, 2011 Interest in the photochemistry and photophysics of pterins has increased since the participation of this family of compounds in different photobiological processes has been suggested or demonstrated in recent decades.

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 ...
