  Thermal stability studies of the non canonical base pair between 5-methyl-isocytosine and isohypoxanthine

  摘要：

  The hybridization properties of 5-methyl-isocytosine ((5Me)isoC) and isohypoxanthine (isoI) have been investigated by using ultraviolet melting techniques. These two bases were incorporated into heptadecanucleotides using the phosphoramidite chemistry. The base pair (5Me)isoC/isoI was found to be isoenergetic with the A/T base pair. A small destabilization was observed when isoI was located opposite T or G and can be interpreted by a pairing mode between these bases and isoI in its lactam form. (C) 1998 Elsevier Science Ltd.
