Adenine forms several tautomers, compounds that can be rapidly interconverted and are often. With low probability these bases can tautomerize into the imino. Web formation of minor tautomers in dna, at low frequency, is proposed to contribute to the phenomenon of ‘spontaneous mutagenesis’, which denotes the background level of. Web the shape of the barrier for the h transfer between the normal and tautomeric forms have been determined for the adenine and thymine molecules. Web in this study, we have investigated 12 tautomers of the dna base adenine at the bp86/tz2p and bp86/qz4p levels of density functional theory. Web cndo/2 calculations predict that while the amine form of adenine should be the most stable one for the n (9)h, n (7)h and n (3)h tautomers of this substance, the inline. Web tautomerization of bases in dna. Web the canonical tautomer a9 is the favored form of neutral adenine in the gas phase and in aqueous solution. Web initially, it was believed that adenine exists mainly in two tautomeric forms (n9h and n7h); Web tautomerism is an important process that can disrupt base pair hydrogen bonding and increases the gene mutations probability.
