<h4><u>NB-Esterase:</u></h4>
+
<h4><u>Flagellin C from <i>Escherichia coli</i> </u></h4>
<p>This enzyme catalyses the degradation of PET into Terephthalic acid (TPA) and Ethylene Glycol. It is the first and slowest reaction of our degradation chain. Indeed, it takes two weeks to degrade PET.</p>
+
<p>Flagellin C (FliC) protein from <i>Escherichia coli</i> strain is the main protein constitutive of the flagelar filament and is involved to promote bacterial swimming. This sequence is conserved in many bacterial strains. It has been demonstrated that Flagellin has the ability to adsorb precious metal such as Platinum, gold...</p>
<p> We performed an enzymatic assay of NB-Esterase using 4-nitrophenylbutyrate as a substrate because it has a close chemical structure to PET and we figured that this enzyme digested pNP in our bacteria</p>
+
<p> We made a FliC mutant by transduction using phage P1 in a <i> E. Coli W3110 </i> strain. Then we have complemented the FliC mutant W3110 with Bba_K151008 and performed a swimming test for every background. The result has shown that swimming was recovered into the complemented FliC mutant W3110</p>

<h4><u>TPA Transporter:</u></h4>
 
<p>The NB-Esterase is present in the extracellular medium and cuts PET in this location. In order to be fully degraded, the TPA needs to be integrated to our chassis organism which is why we incorporated a transporter to our degradation operon.</p>
