| Abstract: | A total gene for eglin C has been chemically synthesized by using the solid phosphoramidite method. The gene is 221 bp in length containing the structure gene encoding 70 amino acids,a start coden ATG at 5'-end and a stop coden TAG at 3'-end of the structure gene,except two restriction sites at the ends. The synthesiS of the gene involved enzymatic joining synthetic oligonucleotiede fragments to form DNA duplexes, cloning into vector M13, idnetifying by dot bloting. Finally,the synthetic coding sequence was fully verified right by dideoxynucleotide chain termination method. |
