Cloning and fusion expression of the antimicrobial peptide thanatin gene in Escherichia coli
The thanatin gene was obtained and inserted into expression vector pGEX-3X by a DNA recombinant method which was checked by nucleotide sequencing. The fusion protein of GST-thanatin was produced by IPTG induction in Escherichia coli (BL21). The expression level was about 20%. The fusion protein was...

Zusammenfassung: | The thanatin gene was obtained and inserted into expression vector pGEX-3X by a DNA recombinant method which was checked by nucleotide sequencing. The fusion protein of GST-thanatin was produced by IPTG induction in Escherichia coli (BL21). The expression level was about 20%. The fusion protein was purified by GST affinity chromatography and digested by enterokinase. Partly purified with Sephadex G-25, the final product, thanatin exhibited antimicrobial activity. |
