Structural precursor of the hemideprotonated guanine pair.

Michael Roitzsch1, Bernhard Lippert.   

Abstract

A pairing scheme (GG7) between two neutral guanine nucleobases taking place via the Watson-Crick faces and involving two bridging water molecules is presented, which upon removal of a H5O2+ entity could convert into the hemideprotonated guanine pair (GG5).
