Wh. Gmeiner et al., NMR-STUDIES SHOW MONOMERIC 5-FLUOROURIDINE FORMS BASE-PAIRS OF INCREASED STABILITY COMPARED WITH URIDINE IN NONAQUEOUS SOLVENTS, Nucleosides & nucleotides, 13(10), 1994, pp. 2329-2344
The binding constants and geometries for nucleoside base pairs involvi
ng 5-fluorouridine (FUr) and adenosine were determined by H-1, C-13, a
nd F-19 NMR to better understand how FUr may perturb RNA structure. 5F
U:A base pairs are more stable than U:A base pairs.
