Sequential single replacement of nucleosides within the decanucleotide d[GGGAATTCCC] (7) by means of a butanediol-1,3 residue allowed us to obtain a set of ten decanucleotides containing vicarious (V) carbonphosphate fragments. These analogues were further used as substrates for svPDE, nuclease PI and EcoR1 endonuclease. Interestingly, replacement of any of the nucleosides within the canonical sequence ...GAATTC... by the butanediol-1,3 vicarious segment discriminates such constructs 8c-h as substrates for Eco-R1 enzyme.
