Gelatinase under pBAD/araC arabinose inducible promoter

Design Notes

The gelE CDS was first isolated from the E. faecalis genome by PCR and the primers used for that also added a His tag at the beginning of the CDS and a linker at the end. Then, a Gibson assembly was performed with our amplified part BBa_I746908 to insert gelE CDS in between the pBAD/araC promoter and superfolder GFP. Bacteria were then transformed with the plasmid, who was isolated and sent for sequencing. This last process allowed us to see that a STOP codon had appeared just before the GFP sequence, after the linker. However, the protein should still be isolate-able since a His-tag was added to it.
