M. Shigeyasu et al., Synthesis and DNA binding property of a novel peptide nucleic acid that contains cis-4-adeninyl-L-prolinol unit, CHEM LETT, (7), 2001, pp. 634-635
A novel oxy-peptide nucleic acid that contains a cis-4-adeninyl-L-prolinol
unit in the main chain (PPNA) was synthesized. The peptide nucleic acid wit
h nine adenine units [PPNA(A,)I hybridized with the complementary DNA (Tg).
The hybrid showed a very sharp melting curve with T-m= 34 degreesC.
