B. Lippert, EFFECTS OF METAL-ION BINDING ON NUCLEOBASE PAIRING - STABILIZATION, PREVENTION AND MISMATCH FORMATION, Journal of the Chemical Society. Dalton transactions, (21), 1997, pp. 3971-3976
Depending on the site of metal binding to a nucleic acid constituent a
nd the geometry of the metal entity, either a stabilization of a nucle
obase ensemble, complementary or not ('metal-modified' base pair, trip
let or quartet), or a prevention of nucleobase pairing may result.
