Usage and Biology
Flavobacterium johnsoniae (formerly Cytophaga johnsonae) is an environmental bacterium that can cause skin lesions in fish and is a plant pathogen.
Origin(organism)
Klebsiella pneumoniae.

Molecular cloning
First, we used the vector pGEX-6p-1 to construct our expression plasmid. And then we converted the plasmid constructed to E. coli DH5α to expand the plasmid largely.
Figure 1. Left: The PCR result of JOHN-1. Right: The verification results by enzyme digestion.
After verification, it was determined that the construction is successful. We converted the plasmid to E. coli BL21(DE3) for expression and purification.
