Systematic study of the tautomerism of uracil induced by proton transfer. Exploration of water stabilization and mutagenicity.

Abstract excerpt

To systematically investigate all the possible tautomerisms from uracil (U) and its enol form (U) induced by proton transfer, we describe a study of structural tautomer interconversion in the gas phase, in a continuum solvent, and in a microhydrated environment with 1 or 2 explicit water molecules, using density functional theory (DFT) calculations by means of the B3LYP exchange and correlation functions. A total...
