An artificial site-selective DNA cutter to hydrolyze single-stranded DNA at a desired site was prepared from Ce(IV)/ethylenediamintetraacetic acid (EDTA) and two ethylenediamine-N,N,N',N'-tetrakis(methylenephosphonic acid)-oligonucleotide conjugates. By using this cutter, the sense strand of a blue fluorescent protein (BFP) gene was selectively cut at a predetermined site in the chromophore-coding region. The upstream fragment obtained by the site-selective scission was ligated with the downstream fragment of the closely related green fluorescent protein (GFP) gene so that the 5'- and 3'-end portions of the chromophore came from the BFP fragment and the GFP fragment, respectively. The recombinant gene was successfully expressed in E. coli and the chimeric chromophore emitted green fluorescence as expected.
