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.

Photosensitization of peptides and proteins by pterin derivatives [PDF]
Pteridines, 2017 Proteins are one of the preferential targets of the photosensitized damaging effects of ultraviolet (UV) radiation on biological system. Pterins belong to a family of heterocyclic compounds, which are widespread in living systems and participate in ...

Paper Chromatography of Pterins [PDF]
Nature, 1949 THE detection and identification of pterins in small quantities was carried out by Schopf and Becker1 in the course of their classical work on this class of pigments. They employed a chromatographic technique using 0·004 N aqueous hydrochloric acid or 0·01 N methyl alcoholic hydrochloric acid solutions on micro-absorption columns of alumina or ...

Mechanistic Study of ROS-photogeneration by Pterin
Pteridines, 2011 Pterins are widespread in biological systems and possess photosensitizing activities. In the present study, the photosensitization mechanism of acid form of pterin (PTA) and basic form of pterin (PTB) is investigated by means of density functional theory

Pterin-based pigmentation in animals. [PDF]
Biol Lett, 2021 Pterins are one of the major sources of bright coloration in animals. They are produced endogenously, participate in vital physiological processes and serve a variety of signalling functions. Despite their ubiquity in nature, pterin-based pigmentation has received little attention when compared to other major pigment classes.

Assessment of Free Energies From Electrostatic Embedding Density Functional Tight Binding-Based/Molecular Mechanics in Periodic Boundary Conditions. [PDF]
J Comput ChemABSTRACT Electrostatic embedding quantum mechanics/molecular mechanics (QM/MM) methods in periodic boundary conditions (PBC) can successfully describe the condensed phase reactivity of a fragment treated at the QM level with an atomistic description of an electrostatic environment treated at the MM level.
