We have synthesized, separated, and purified approximately 10 mg of a deoxyundecanucleotide duplex containing single centrally positioned covalent adduct between (+)-anti-benzo[a]pyrene (BP) diol epoxide the exocyclic amino group guanosine. Excellent proton NMR spectra are observed for (+)-trans-anti-BP epoxide-N2-dG opposite dC flanked by G.C pairs in d[C1-C2-A3-T4-C5-(BP)G6-C7-T8-A9-C10-C11].d[12- G13-T14-A15-G16-C17-G18-A19-T20-G 21-G22] +ADdesignated (BP)G.C 11-mer+BD. determined...

[5,8-13C2]Spermidine was prepared by synthesis, and its binding to macromolecular structures of Escherichia coli studied. When added E. cells, the two signals [13C]spermidine (C-5, 47.8 ppm, C-8, 39.6 ppm; JC-C = 5.8 Hz) were strongly broadened due macromolecules. tRNA, C-5 resonance v1/2 4.7 Hz, whereas C-8 2.7 Hz. tRNA-bound could be chased [12C]spermidine or spermine, but not putrescine cadaverine. By using mixtures [5-13C]- [8-13C]spermidines (where 13C-13C coupling avoided), it possible...
Translesional DNA synthesis past abasic sites proceeds with the preferential incorporation of dAMP opposite lesion and, depending on sequence context, one or two base deletions. High-resolution NMR spectroscopy and molecular dynamics simulations were used to determine three-dimensional structure a heteroduplex containing synthetic site (tetrahydrofuran) residue positioned in that promotes Analysis spectra indicates stem region duplex adopts right-handed helical glycosidic torsion angle is...
