Energetic contribution from aromatic π-π stacking to the stabilization of DNA/RNA is not small and sometimes even comparable to that from H-bonding. The basis of the stacking interactions lies in the π-electron structure of individual nucleobases, which can be described by various aromaticity indices. Heteroatoms and exocyclic functional groups make the electronic structure of nucleobases different from aromatic hydrocarbons. Consequently, the cyclic π-electron delocalization is not the only factor responsible for the relative stability of their tautomers. This Review puts the spotlight on interplay between aromaticity of purine and pyrimidine nucleobases and their tautomeric preferences, as well as on the effects of different noncovalent interactions (hydrogen bonding, metal ion coordination, and π-π stacking) on π-electron delocalization of five- and six-membered rings in individual nucleobases and their complexes" , "dc.description.sponsorship": "Generalitat de Catalunya, Grant/AwardNumber: 2017-SGR-39; Ministerio deEconomía y Competitividad, Grant/AwardNumbers: CTQ2017-85341-P, FJCI-2017-32757; Narodowe Centrum Nauki,Grant/Award Number: UMO-2016/23/B/ST4/00082" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "Wiley" , "dc.relation.isformatof": "Versió postprint del document publicat a: https://doi.org/10.1002/wcms.1509" , "dc.relation.ispartof": "© WIRES Computational Molecular Science, 2021, vol. 11, núm. 4, p. e1509" , "dc.relation.ispartofseries": "Articles publicats (D-Q)" , "dc.rights": "Tots els drets reservats" , "dc.source": "Szatylowicz, Halina Stasyuk, Olga A.
