Single atom modification leads to enhanced nucleotide self-assembly: the role of cation bridging

We report that the ability of disodium 5'-deoxy-5'-thioguanosine-5'-monophosphate, Na(2)(5'-GSMP), to self-associate into a helical G-quadruplex structure in aqueous solution at pH 8 is significantly higher than that of disodium guanosine-5'-monophosphate, Na(2)(5'-GMP)...

description We report that the ability of disodium 5'-deoxy-5'-thioguanosine-5'-monophosphate, Na(2)(5'-GSMP), to self-associate into a helical G-quadruplex structure in aqueous solution at pH 8 is significantly higher than that of disodium guanosine-5'-monophosphate, Na(2)(5'-GMP), which supports our earlier hypothesis regarding the importance of cation bridging.
