Applications of BBa_K533003

Like BBa_I712667, it can specifically cleave proteins in the peptide. The difference is that it is expressed as a membrane protein, which enables it to cut target proteins in the media.

We tested function of the protease with OmpA-HIV protese site-SH3, our part BBa_K533002.

E. coli expressing OmpA-HIV protease site-SH3 were first mixed up in multi-proline mCherry, to give it the red fluorescence marker. After washing with distilled water twice, the remaining bacteria were mixed with E. coli expressing OmpA-HIV protease at room temperature for 30 minutes to release the cargo.

After washing with distilled water twice, bacteria were fixed on a slip and stained with DAPI.
