Core-Level Spectroscopy of 2-Thiouracil at the Sulfur L₁- and L_2,3-Edges Utilizing a SASE Free-Electron Laser

Molecules, 2021
In this paper, we report X-ray absorption and core-level electron spectra of the nucleobase derivative 2-thiouracil at the sulfur L1- and L2,3-edges. We used soft X-rays from the free-electron laser FLASH2 for the excitation of isolated molecules and ...

Fungal nucleobase transporters [PDF]

FEMS Microbiology Reviews, 2007
Early genetic and physiological work in bacteria and fungi has suggested the presence of highly specific nucleobase transport systems. Similar transport systems are now known to exist in algae, plants, protozoa and metazoa. Within the last 15 years, a small number of microbial genes encoding nucleobase transporters have been cloned and studied in great
