Reverse Watson−Crick Isocytosine−Cytosine and Guanine−Cytosine Base Pairs Stabilized by the Formation of the Minor Tautomers of Bases. An ab Initio Study in the Gas Phase and in a Water Cluster
The inclusion of the GC base pair into parallel stranded (ps) DNA requires a counterrotation of the two bases by 180° with respect to the standard Watson−Crick (WC) arrangement. This brings the two amino groups into close contact and leads also to a repulsive interaction between the two carbonyl gro...
