We fused amilCP to the signal peptide Kp-Sp from actinomycetes and transferred the plasmid into E. coli BL-21. Incubate overnight in LB medium at 37 ° C, 200 rpm. The control group was an amilCP without the fusion signal peptide Kp-Sp. 15 ml of the bacterial solution was taken from each group and centrifuged at 8000 rpm. It was observed that the supernatant of the experimental group showed a clear blue color, the supernatant of the control group had no color, and the value of OD588 was measured. After that, we collected the bacteria of the experimental group. | We fused amilCP to the signal peptide Kp-Sp from actinomycetes and transferred the plasmid into E. coli BL-21.

The signal peptide Kp-SP was added to the N-terminus of amilCP
The secreting peptide Kp-SP was added to the N-terminus of the pigment protein - amilCP, and realized the transition of the amilCP from intracellular to extracellular.
Usage and Biology
We fused amilCP to the signal peptide Kp-Sp from actinomycetes and transferred the plasmid into E. coli BL-21. Incubate overnight in LB medium at 37 ° C, 200 rpm. The control group was an amilCP without the fusion signal peptide Kp-Sp. 15 ml of the bacterial solution was taken from each group and centrifuged at 8000 rpm. It was observed that the supernatant of the experimental group showed a clear blue color, the supernatant of the control group had no color, and the value of OD588 was measured. After that, we collected the bacteria of the experimental group.
We used ultrasonic lysis to measure OD588 using a microplate reader. We found that about 30% of amilCP was secreted outside the cell.
