Mercuric complex of guanosine 5'-monophosphate

Time-resolved probes and oxidase-based biosensors using terbium(iii)–guanosine monophosphate–mercury(ii) coordination polymer nanoparticles

“…13 Hg 2+ can complex with guanosine molecules, 14 and formation of the complex requires the amino group of the guanine moiety and the phosphate group of GMP. 15 And Hg 2+ is known to be an efficient luminescent quencher. 16 In this respect, we proposed that the introduction of Hg 2+ into Tb-GMP can be realized via the interaction between Hg 2+ and GMP, and the as-prepared ternary Tb-GMP-Hg would have low luminescence, resulting from the luminescent quenching effect of Hg 2+ .…”

Calculation of the Effects of Hydration and Divalent Metal Ions on Nucleotide Base Pairs: Single G–C and Poly(G–C)

“…8 The effects of metal ions on the ultraviolet absorption spectra of DNA components have also been clearly demonstrated. 9 Similarly it is well known that water molecules are ever present in and around DNA molecules in the living cell. When we talk about metal-ion binding to DNA, we must distinguish between binding to the phosphate group of the chain and binding to the heterocyclic base sites.…”

“…12, 59, 66 (1959 (1960). 9 Since we have two base pairs in the unit cell, the matrix (3 contains also such elements which are resonance integrals between AO's belonging to two different superimposed bases. Therefore they were estimated on the basis of overlap integrals which depend on the relative positions of t and s. 10 Since the relation R,,8+= R",holds, we also have ')'".+= ')'",-, (3",+=(3",-, P",+=P",which greatly simplifies the calculations.…”
