NonStd Res: 0UH Resources: FirstGlance, OCA, RCSB, PDBsum Publication Abstract from PubMed What a pentaplexing situation: Isoguanine (iG) is an isomer of guanine, where the positions of the C2 amino group and the C6 carboxy group are swapped. iG can self-assemble into pentads in the presence of alkali metal cations. Cs(+) ions were found to stabilize a pentaplex of d(T(iG)(4) T). Solution NMR studies of this pentaplex in the presence of Cs(+) ions (or Na(+) , K(+) , Rb(+) , or NH(4) (+) cations) demonstrate its stability and structure.
