Metal ion catalysis of proton exchange between purine nucleosides or nucleotides and solvent water
Abstract
Co-ordination of the methylmercury(II) cation at N-7 of inosine and guanosine-5′-phosphate catalyses proton exchange between the proton bound to C-8 and the solvent water leading to disappearance of the 1H n.m.r. singnal in D2O.
