Photocrosslinking of 4-thio uracil-containing RNAs supports a side-by-side arrangement of domains 5 and 6 of a group II intron.

RNA 5(2) , 318-29, (1999)

Previous studies suggested that domains 5 and 6 (D5 and D6) of group II introns act together in splicing and that the two helical structures probably do not interact by helix stacking. Here, we charac...

Photoelectron spectroscopic study of the negative ions of 4-thiouracil and 2,4-dithiouracil.

J. Chem. Phys. 134(7) , 074304, (2011)

We report the photoelectron spectra of the negative ions of 4-thiouracil (4-TU)(-) and 2,4-dithiouracil (2,4-DTU)(-). Both of these spectra are indicative of valence anions, and they are each dominate...

Mechanism and dynamics of intramolecular triplet state decay of 1-propyl-4-thiouracil and its α-methyl-substituted derivatives studied in perfluoro-1,3-dimethylcyclohexane.

Photochem. Photobiol. Sci. 10(8) , 1294-302, (2011)

Zinc deficiency is causing malnutrition for nearly one third of world populations. It is especially relevant in cereal-based diets in which low amounts of mineral and protein are present. In biologica...
