Part:BBa_K2599000
Antimicrobial peptide - Subtilosin
This biobrick is the basic part of the Subtilosin (BBa_K2599008).

Introduction
Bacillus subtilis produces a bacteriocin called Subtilosin that possesses antibacterial activity against certain gram-positive bacteria. The bacteriocins are a group of anitmicrobial peptides that are often distinguished from traditioinal antibiotics by their narrow range of avtivity against closely related bacteria.
Experiment Result
Cloning
We conbined our toxic gene to pSB1C3 backbone and conducted PCR to check the size of our part. The Subtilosin sequence length is around 147 b.p. For the composite part, the sequence length should be near at 1191 b.p.
Figure 2 PCR
Expressing
We chose E. coli 2566 strain to express our antibacterial peptides. The expression of Subtilosin fused with intein was induced by IPTG in E. coli , and intein-subtilosin specifically bound to the column through chitin binding domain would be purified.
