HyLα: Hybrid peptide of LL-37 and LTA

LL-37 and LTA are both affective antimicrobial peptides (AMPs). HyLα successfully combine those two AMPs by connecting the C-terminate of LTA with the N-terminate of LL-37 through GS-linker. It could neutralize Lipopolysaccharides (LPS), thus effectively blocking the downstream inflammation pathway.


Design

The plasmid we designed consists of T7 promoter, lac operator, RBS, HyLα coding sequence, His tag and T7 terminator, which are arranged in an order on a pET28 backbone. We aim to induce the transcription of the downstream HyLα by adding the IPTG to initiate the expression. The protein will then be purified and antibacterial activity was tested by culturing the Salmonella enterica subsp. Enterica (ex Kauffmann and Edwards) Le Minor and Popoff serovar Typhimurium with our purified HyLα and measuring the OD600 to reflect the bacteria growing condition. This part has undergone codon optimization based on the bias of Escherichia coli.
