Abstract: The objective of this test was to make a prokaryotic express of the bacteriophage RAP44 lysin gene of Riemerella anatipestifer. The gene of lyase was amplified by PCR using genomic DNA of bacteriophage RAP44 and inserted into pGEX-6P-1 vector. The constructed recombinant plasmid was transformed into Escherichia coli BL21(DE3) to express fusion protein, which was purified by Glutathione-Sepharose 4B. The results showed that expression plasmid pGEX-N was constructed successfully. The soluble recombinant protein about 37 kD was expressed after induced by IPTG. The purified fusion protein was generated in this study, which laid a foundation for the functional study of bacteriophage lysin of Riemerella anatipestifer.
