Well we found the gene; we analyzed and looked for the sequence of the restriction sites of E, X, P and S. Sadly we found the sequence of the PstI. That definitely is a setback, but thanks to mutagenesis, we can solve this problem. We designed a set of primers, for the amplification of the Rhabl gene. For mutagenesis of our gene we chose the Stratagene lightning mutagenesis kit, and we also designed another set of primers. Before this we analyzed the gene and checked the reading frame and verified which base pair we can change without changing de amino acids sequence.

Finally, we define our project!

Our goal is the development of a genetically engineered E. coli that can produce rhamnosyltranferase 1 enzyme. These are the steps we follow for our project design:

1. First we look for information regarding the biosurfactant production and we found a paper that describes the Rhlab gene.

2. This gene is found in the Pseudomonas aeruginosa.

3. We search the Rhlab gene sequence in GeneBank, here are the accession numbers: Rhla (Gene ID: 878955) LOCUS NC_002516 888 bp DNA

Rhlb (Gene ID: 878954) LOCUS NC_002516 1281 bp DNA

4. The next step was the RhlAB gene sequence analysis, we found THREE PstI recognition sequenceS. After this we designed two different set of primers for the RhlAB amplification from the P. aeruginosa genomic DNA.

5. We began an extensive research for an easy, fast and cheap mutagenesis kit. Thankfully we found the QuikChange Lightning MultiSite-Directed Mutagenesis Kit (Catalog #210513 and #210515)

6. For the mutagenesis protocol we also designed three different set of primers (we use the QuickChange Primer design tool from Agilent Technologies), because the base pairs that surround the PstI unwanted sequence were different. Nevertheless, before we design the primers we analyzed the Rhlab codon sequence, because we want to performed silent mutations (change the codon but not the amino acid).
