Structural-energetic peculiarities of spontaneous examination of ca¬nonical nucleotide bases and their modified analogues

D. M. Hovorun

By the semiempirical quantum-chemical AMI method there were investigated energetic (enthalpy) and structural (variation in stereochemical non-rigidity and tautomeric state) peculiarities of spontaneous deamination of canonical nucleotide bases and number of their biologically important modified analogues which have exocyclic aminogroup in their composition.
