Biology

This is a combination of SE (BBa_K3740042) and IMM (BBa_K3740034) into device, that is used to regulate the expression of SE and IMM.

Usage

We connected PA1/04/03-RBS150-SE-B1006（BBa_K3740054）and J23118-RBSII-IMM-rrnB T1 (BBa_K3740053) to the expression vector pSEVA331 by standard assembly, and introduced the connection mixture into G. haensenii ATCC 53582. When the engineering bacteria were lysed, SE protein can be released to kill Pseudomonas aeruginosa specifically.

Characterization

1. Verification of SE protein antibacterial performance of composite parts

As shown in (a), the lysis supernatant of PA1/04/03-RBS150-SE-B1006-J23118-RBSII-IMM-rrnB T1-pSEVA331-G. hansenii ATCC 53582-2# has an inhibitory effect on the growth of PAO1; In (b), the lysis supernatant produced a zone of inhibition, but the effect was not very obvious. These results show that expression of SE protein was successfully induced in G. hansenii ATCC 53582 and indicated that PA1/04/03-RBS150-SE-B1006-J23118-RBSII-IMM-rrnB T1-pSEVA331-G. hansenii ATCC 53582-2# has an inhibitory effect on PAO1, but the effect is not very obvious.
