Some new derivatives of Ni(II) with uracil, uridine and nucleotides
Inorganica Chimica Acta, 1986Abstract This paper describes the synthesis of compounds of Ni(II) with uracil, uridine and the nucleotides 5′UMP, 5′CMP, 5′GMP and 5′IMP, and their characterization, carried out by elemental analysis, by studying the infrared spectra, diffuse reflectance and conductivity measurement.

Proton magnetic resonance data for uridine and uridine-5′-monophosphate, and the corresponding 6-azauracil analogs, are presented and discussed in terms of their overall three dimensional conformations in aqueous solution. The data reveal a destabilizing influence of the 6-aza base upon the gog and g′–g′ conformation of the ribose phosphate moiety.

Glomerular uracil nucleotide synthesis
American Journal of Physiology-Renal Physiology, 1988The biosynthesis of basement membrane material requires the sugar derivatives of uridine 5'-triphosphate (UTP) for protein glycosylation. Uridine and orotate utilization for the biosynthesis of uracil ribonucleotides was studied in isolated rat glomeruli incubated in vitro. At a 1 microM concentration total orotate utilization was 9.6 +/- 1.8 pmol.min-

Acidity of a Nucleotide Base: Uracil
The Journal of Physical Chemistry A, 2004Experiment and calculations are used to show that the gas-phase acidity of uracil is comparable to that of HCl. The gas-phase acidity of uracil (denoted here by U) was bracketed by proton-transfer measurements involving Uand various reference acids (denoted here by A) of known gas-phase acidity.

Recognition of an Unnatural Difluorophenyl Nucleotide by Uracil DNA Glycosylase
Biochemistry, 2004The DNA repair enzyme uracil DNA glycosylase (UDG) utilizes base flipping to recognize and remove unwanted uracil bases from the genome but does not react with its structural congener, thymine, which differs by a single methyl group. Two factors that determine whether an enzyme flips a base from the duplex are its shape and hydrogen bonding properties.

The Bacillus subtilis bacteriophages PBS-1 and PBS-2 protect their uracil-containing DNA by expressing an inhibitor protein (UGI) which inactivates the host uracil-DNA glycosylase (UDGase) base-excision repair enzyme. Also, PBS1/2 UGI efficiently inactivates UDGases from other biological sources, including the enzyme from herpes simplex virus type-1 ...
