Schiff base-mediated base pairing [PDF]

Nucleic Acids Symposium Series, 2005
We here present a novel covalently linked base pair via Schiff base formation between 5-formyluracil (fU) and 5-aminocytosine (AmC). The formation of Schiff base remarkably increases thermal stability of the duplex DNA, whereas it completely dissociates upon heating at 90 degrees C. Neither AmC nor fU produces covalent linkage with other natural bases,
