Abstract
2′,4′-Dideoxy-4′-methyleneuridine incorporated into oligodeoxynucleotides forms regular B-DNA duplexes as shown by Tm and CD measurements. Such oligomers are not cleaved by the DNA repair enzyme, UDG, which cleaves the glycosylic bond in dU but not in dT nor in dC nucleosides in single stranded and double stranded DNA. Differential binding of oligomers containing carbadU, 4′-thiodU, and dU residues to wild type and mutant UDG proteins identify an essential role for the furanose 4′-oxygen in recognition and cleavage of dU residues in DNA.
