WebbIn order to gain deeper insight into structure, charge distribution, and energies of A-T base pairs, we have performed quantum chemical ab initio and density functional calculations at the HF (Hartree-Fock) and B3LYP levels with 3-21G*, 6-31G*, 6-31G**, and 6-31++G** basis sets. The calculated donor … WebbWe conclude that thymine isosteres F and L - and thymine itself - benefit from this shape complementarity with A. Indeed, our computations show that all three have no inherent pairing preference for adenine, and thus the steric fit of the pair within the Watson-Crick backbone context explains essentially all of the selectivity.

Webb21 feb. 2024 · Thymine dimer induced bending: The DNA bend angle θ 0 is measured after energy minimization is carried out on a 40-bp DNA duplex that contains a thymine dimer (in cyan). The angle θ 0 is defined by first assigning each base pair on the DNA into one of two groups, depending on which side of the thymine dimer it is located. Lines are then fitted … WebbPubChem Substance ID: 24891565. NACRES: NA.77. Recommended Products. Slide 1 of 10. 1 of 10. Sigma-Aldrich. B2883. bisBenzimide H 33258. ≥98% (HPLC and TLC) ...
