Used for comparison with BBa_K4183002 to test the efficiency of secreted signal peptide.

Used for comparison with BBa_K4183002 to test the efficiency after the addition of the secreted signal peptide at the N-terminal end of lacZ.

Usage and Biology

We coated the engineered EcN bacteria containing BBa_K4183003 on LB agar plates containing IPTG as well as X-Gal and incubated them overnight at 37°C. The results showed that the breakdown of X-Gal could be clearly observed around the monoclonal colonies (Figure 1), which proved that lacZ was secreted extracellularly.

(A) When the N-terminal end of lacZ did not contain kp-sp, no disassembly of X-Gal was clearly observed around the monoclonal colonies. (B) When the N-terminal end of lacZ contains kp-sp, X-Gal is clearly observed to be disassembled around the monoclonal colony, showing a blue color.
