A report, 'Promotion of rare nucleobase tautomers by metal binding,' is newly published data in Dalton Transactions. "Metal binding to ligands with the potential of existing in different tautomeric structures can dramatically alter the tautomeric equilibrium by stabilizing a particular, frequently minor, tautomer. The assumption that metal complexation of a minor tautomer is chemically irrelevant because of its very low abundance is misleading and in many cases wrong," scientists in Dortmund, Germany report (see also Life Sciences).
"In fact, from available X-ray structural data on metal-nucleobase complexes it is evident that metal binding to rare, as opposed ...
