[46]. The similarity in the Kmvalues is attributable to the uracil moiety binding in the same fashion [38], which could trigger the initialbinding of both substrates. In UpG, the binding of the guanine ... mononucleo-sides and two dinucleosides containing an N-acylsulf-onamide linker [R–S(O2)–NH–C(O)–R¢], which hasthree nonbridging oxygens, in the place of a phos-phoryl group. Finally, we determined the...
