Guanine-vacancy–bearing G-quadruplexes responsive to guanine derivatives [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance Guanine-rich nucleic acids fold into a four-stranded structure named G-quadruplex that has implications in essential cellular processes, pharmaceutical applications, and nanodevices. We found a unique type of G-quadruplex that contains a G-vacancy and is stabilized by guanine derivatives such as te physiological concentration of ...
