<p>We began our project by identifying a range of BioBrick parts present in the iGEM 2014 distribution kit which we required as part of our cloning strategy. These parts primarily consisted of both constituitive and inducible promoter systems with ribosome binding sites which we could then use in conjunction with our azo-reductase BioBricks to assemble a functional azo dye degrading gene. We also decided that we would use the Red Florescent Protein expressing BioBrick as a control for any further transformation experiments. As the level of DNA present within each plate of the distribution kit is insufficient to perform digest and ligation reactions on it was necessary to transform each of these plasmids into our NEB5alpha competent cells. After growing our transformed cells overnight we then mini-prepped each of them to obtain BioBrick plasmids at suitable concentrations for future experiments.</p><br>

                        <tr>

    <p>Searching through the literature, we identified a number of bacterial species (including <em>Bacillus subtilis</em> and <em>Pseudomonas sp.</em>) that have proven to degrade azo dye compounds <a href="http://www.ncbi.nlm.nih.gov/pubmed/21655981">[1]</a><a href="http://www.ncbi.nlm.nih.gov/pubmed/24475252">[2]</a><a href="http://www.itqb.unl.pt/martins/index_files/JBC2002.pdf">[3]</a><a href="http://www.ncbi.nlm.nih.gov/pubmed/23820555">[4]</a>. <br>

    We contacted the <a href="http://www.itqb.unl.pt/martins">Microbial & Enzyme Technology Lab</a> led by Dr Lígia O. Martins at the Universidade Nova de Lisboa, who are currently researching how azo dye degrading enzymes function, and they were keen to collaborate with us on our project. They agreed to send us a set of five plasmids, each containing different genes encoding azo dye degrading enzymes from both <em>B. subtilis</em> and <em>P. putida</em> (including mutated forms found to exhibit enhanced degradation activity), for us to use in our investigations (see Table below). <br>

                 <p>Our literature search identified a number of bacterial species that have been proven to degrade azo dye compounds including <i>B. subtilis</i> and <i>P. aeruginosa</i>. We were able to obtain a <i>B. subtilis</i> strain for use in our project from ?.  We extracted the genomic DNA from this strain using a Promega Wizard Genomic DNA extraction kit so that we could subsequently amplify the azo-reducatase gene (AzoR1) and create our first azo-reductase BioBrick.  After completing the genomic DNA extracton we ran a gel to show that we had successfully extracted the <i>B. subtilis</i> genomic DNA.</p>

    <p>The five azo dye degrading enzymes from Lisbon arrived as the respective genes in pET-21a (+) ampicillin resistant (ampR) expression vectors/plasmids (size: 5443 bp)<a href="http://www.addgene.org/browse/sequence_vdb/2549/ ">[1]</a><a href=" http://biochem.web.utah.edu/hill/links/pET21.pdf">[2]</a>. The DNA concentrations of these plasmids, however, were insufficient to perform PCR amplification, therefore we transformed each into our own <em>E. coli</em> competent cells (grown from NEB DH5&alpha; derivatives). After growing the cells overnight, we made bacterial glycerol stocks and miniprepped the cells to obtain plasmids at sufficient concentrations for further work.</p>

    <p>A diagnostic digest was performed to ascertain that these pET-21a (+) plasmids contained the gene we expected. As each plasmid possessed <em>EcoRI</em> and <em>XbaI</em> restriction sites close to the genes of interest, we performed double-digests using these recognition enzymes and predicted the digest fragments. The digestion products were visualised using gel electrophoresis (see image right). </p>

    <p>Achieving a successful PCR proved difficult; this may have been due to poor PCR reagent quality. We repeated the PCR using various polymerases (Taq, Phusion and Pfu) and also different dNTP mixes. Eventually, we succeeded in amplifying AzoR 1B6, BsDyP, and ispB asDNA with the required BioBrick Prefix and Suffix.

    <p>Our next step was to ligate these into the required pSB1C3 backbone. For BsDyP and ispB asDNA, this proved to be fairly straightforward, and quickly resulted in the production of our first new BioBricks: <a href="http://parts.igem.org/Part:BBa_K1336003">BBa_K1336003</a> for BsDyP+pSB1C3, and <a href="http://parts.igem.org/Part:BBa_K1336005">BBa_K1336005</a> for ispB+pSB1C3.<br>

    This was trickier for 1B6, as this gene possessed 2 illegal <em>PstI</em> restriction sites. <a href="https://2014.igem.org/Team:UCL/Science/Primers">Site-directed mutagenesis primers</a> were designed to remove these sites, however, we could not completed this in time for submission. We did, however, succeed in performing a directionless ligation into pSB1C3. From here, we screened for plasmids with the correct orientation, and started our characterisation assays with this pseudo-BioBrick part.</p>

 +
<p>
 +
    We decided to assemble both BsDyP and ispB in a LacI cassette, inducible by IPTG.
 +
Issues with inconclusive antibiotic effectivity led to major delays in construction of these composite parts. We first had to prove our antibiotics were functioning properly before making progress on our project.</p><br/>
 +
<p>We confirmed the construction of our BsDyP and ispB cassettes using analytical gel digest cutting at sites E and P.</p>
 +
<br>
 +
<p>Ideally, we wanted a Azo-Remediation Chassis (ARC), our BioBrick System, to be assembled as follows:</p><br>
 +
<div><center><a data-tip="true" class="top large" data-tip-content="Here's our prototype Azo-Remediation Chassis!" href="javascript:void(0)" style="width: 100%;margin-left:1%;"><img src="https://static.igem.org/mediawiki/2014/0/07/UCL_Chassis.png" style="max-width: 80%;"></a></center></div><br>
 +
    <p>A further development on this prototype would be to have Bba_K1336000, the AzoR gene, to be inducibly transcribed by one promoter (say BBa_K314103, the LacI Expression Cassette) such that it is expressed in the reductive step of our azo dye remediation process. This would form a distinct BioBrick Device of "promotor A + AzoR + double terminator". <br>A secondary BioBrick Device (of "promoter B + gene 2 + double terminator") would follow this, where gene 2 would be one of our enzymes that function in the oxidative step of the azo dye remediation process, e.g. laccase or one of the dye decolourising peroxidases. A further tertiary BioBrick Device, with another oxidative enzyme would also be ideal. At least 2 oxidative enzymes are proposed as the enzymes are specialised for different substrates (as described in our <a href="/Team:UCL/Project/Biobricks">BioBrick</a> page. </br>
 +
        As always, time works against us, and we succeeded only in constructing 2 composite parts (BioBrick Devices): <a href="http://parts.igem.org/Part:BBa_K1336007">BBa_K1336007</a> for LacIEC+BsDyP+pSB1C3, and <a href="http://parts.igem.org/Part:BBa_K1336006">BBa_K1336006</a> for LacIEC+ispB+pSB1C3. This latter ispB asDNA device has functions in the <a href="/Team:UCL/Project/Xenobiology">biosafety aspects</a> of our ARC.</p>

        <p>Our literature search identified a number of bacterial species that have been proven to degrade azo dye compounds including <i>B. subtilis</i> and <i>P. aeruginosa</i>.  We were able to obtain a <i>B. subtilis</i> strain for use in our project from ?.  We extracted the genomic DNA from this strain using a Promega Wizard Genomic DNA extraction kit so that we could subsequently amplify the azo-reducatase gene (AzoR1) and create our first azo-reductase BioBrick.  After completing the genomic DNA extracton we ran a gel to show that we had successfully extracted the <i>B. subtilis</i> genomic DNA.</p>

        <p>We were gratefully provided with a set of five plasmids from a group of researchers working at the University of Lisbon, Portugal who are researching how azo-dye degrading enzymes function and who were keen to collaborate with us.  These plasmids contained a number of genes encoding azo-dye degrading enzymes from both <i>B. subtilis</i> and <i>P. putida</i>  including mutated forms found to exhibit enhanced degradation activity.  As the DNA concentration of the plasmids we were sent was insufficient to perform PCR amplification on we transformed each of these plasmids into our <i>E. coli</i> NEB5alpha competent cells.  After growing the cells overnight we then mini-prepped each of them to obtain plasmids at sufficient concentrations for future experimental work.</p>

Stage 01: Extraction of Useful BioBrick Plasmids from iGEM 2014 Distribution Kit


We began our project by identifying a range of BioBrick parts present in the iGEM 2014 distribution kit which we required as part of our cloning strategy. These parts primarily consisted of both constituitive and inducible promoter systems with ribosome binding sites which we could then use in conjunction with our azo-reductase BioBricks to assemble a functional azo dye degrading gene. We also decided that we would use the Red Florescent Protein expressing BioBrick as a control for any further transformation experiments. As the level of DNA present within each plate of the distribution kit is insufficient to perform digest and ligation reactions on it was necessary to transform each of these plasmids into our NEB5alpha competent cells. After growing our transformed cells overnight we then mini-prepped each of them to obtain BioBrick plasmids at suitable concentrations for future experiments.

Stage 02: Identification of Useful Genes for Making New BioBricks


Identifying Azo-Dye Degrading Enzymes

Searching through the literature, we identified a number of bacterial species (including Bacillus subtilis and Pseudomonas sp.) that have proven to degrade azo dye compounds [1][2][3][4].
We contacted the Microbial & Enzyme Technology Lab led by Dr Lígia O. Martins at the Universidade Nova de Lisboa, who are currently researching how azo dye degrading enzymes function, and they were keen to collaborate with us on our project. They agreed to send us a set of five plasmids, each containing different genes encoding azo dye degrading enzymes from both B. subtilis and P. putida (including mutated forms found to exhibit enhanced degradation activity), for us to use in our investigations (see Table below).


Gene ID Name / Function Source Size Plasmid
 pAzoR  FMN-dependent NADH-azoreductase 1  Pseudomonas putida  612 bp  In expression vector: pET-21a (+) (ampicillin resistant) [2] [3] ,
initially cloned between NdeI and BamHI restriction sites.
 p1B6  AzoR Heat-stable Mutant  Pseudomonas putida  612 bp  In expression vector: pET-21a (+) (ampicillin resistant) [2] [3] ,
initially cloned between NdeI and BamHI restriction sites.
 pCotA  Spore Coat Protein Laccase  Bacillus subtilis  1542 bp  In expression vector: pET-21a (+) (ampicillin resistant (ampR)) [2] [3] ,
initially cloned between NheI and BamHI restriction sites.
 pBsDyP  Dye Decolourising Peroxidase BSU38260  Bacillus subtilis  1251 bp  In expression vector: pET-21a (+) (ampicillin resistant) [2] [3] ,
initially cloned between NdeI and BamHI restriction sites.
 pPpDyP  Dye Decolourising Peroxidase PP_3248  Pseudomonas putida  864 bp  In expression vector: pET-21a (+) (ampicillin resistant) [2] [3] ,
initially cloned between NdeI and BamHI restriction sites.

Extraction of B. Subtilis Genomic DNA
Protocols   DNA extraction

In the meantime, Helina (in our team), was able to obtain B. subtilis and P. aeruginosa strains for us to test whether we could retrieve azo dye degrading enzymes from their genomes, specifically, the azo-reductase gene (AzoR). This would be the first step for our first azoreductase BioBrick.
We extracted the genomic DNA from B. subtilis strain using a Promega Wizard Genomic DNA extraction kit so that we could subsequently amplify the azoreducatase gene (AzoR1) and create our first azoreductase BioBrick. After completing the genomic DNA extracton we ran a gel to show that we had successfully extracted the B. subtilis genomic DNA.



Stage 03: Transforming E. coli with Azo-Dye Degrading Plasmids from Lisbon


Transforming E. coli with Azo-Dye Degrading Plasmids

The five azo dye degrading enzymes from Lisbon arrived as the respective genes in pET-21a (+) ampicillin resistant (ampR) expression vectors/plasmids (size: 5443 bp)[1][2]. The DNA concentrations of these plasmids, however, were insufficient to perform PCR amplification, therefore we transformed each into our own E. coli competent cells (grown from NEB DH5α derivatives). After growing the cells overnight, we made bacterial glycerol stocks and miniprepped the cells to obtain plasmids at sufficient concentrations for further work.


Diagnostic Digest of Azo-Dye Degrading Plasmids
Protocols   digest gel

A diagnostic digest was performed to ascertain that these pET-21a (+) plasmids contained the gene we expected. As each plasmid possessed EcoRI and XbaI restriction sites close to the genes of interest, we performed double-digests using these recognition enzymes and predicted the digest fragments. The digestion products were visualised using gel electrophoresis (see image right).







Stage 04: Creation of Azo-Reductase BioBrick Parts from Plasmids


Protocols   analytical digest gel

After isolating our genes of interest we attempted to use PCR as a method of prefix and suffix generation to fit the BioBrick standard assembly parts format.


Achieving a successful PCR proved difficult; this may have been due to poor PCR reagent quality. We repeated the PCR using various polymerases (Taq, Phusion and Pfu) and also different dNTP mixes. Eventually, we succeeded in amplifying AzoR 1B6, BsDyP, and ispB asDNA with the required BioBrick Prefix and Suffix. Given the time-constraints, we did not succeed in also amplifying AzoR, CotA, and PpDyP with the Prefix and Suffix.



Our next step was to ligate these into the required pSB1C3 backbone. For BsDyP and ispB asDNA, this proved to be fairly straightforward, and quickly resulted in the production of our first new BioBricks: BBa_K1336003 for BsDyP+pSB1C3, and BBa_K1336005 for ispB+pSB1C3.
This was trickier for 1B6, as this gene possessed 2 illegal PstI restriction sites. Site-directed mutagenesis primers were designed to remove these sites, however, we could not completed this in time for submission. We did, however, succeed in performing a directionless ligation into pSB1C3. From here, we screened for plasmids with the correct orientation, and started our characterisation assays with this pseudo-BioBrick part.


Stage 05: Assembly of BioBrick Devices


We decided to assemble both BsDyP and ispB in a LacI cassette, inducible by IPTG. Issues with inconclusive antibiotic effectivity led to major delays in construction of these composite parts. We first had to prove our antibiotics were functioning properly before making progress on our project.


We confirmed the construction of our BsDyP and ispB cassettes using analytical gel digest cutting at sites E and P.


Ideally, we wanted a Azo-Remediation Chassis (ARC), our BioBrick System, to be assembled as follows:



A further development on this prototype would be to have Bba_K1336000, the AzoR gene, to be inducibly transcribed by one promoter (say BBa_K314103, the LacI Expression Cassette) such that it is expressed in the reductive step of our azo dye remediation process. This would form a distinct BioBrick Device of "promotor A + AzoR + double terminator".
A secondary BioBrick Device (of "promoter B + gene 2 + double terminator") would follow this, where gene 2 would be one of our enzymes that function in the oxidative step of the azo dye remediation process, e.g. laccase or one of the dye decolourising peroxidases. A further tertiary BioBrick Device, with another oxidative enzyme would also be ideal. At least 2 oxidative enzymes are proposed as the enzymes are specialised for different substrates (as described in our BioBrick page.
As always, time works against us, and we succeeded only in constructing 2 composite parts (BioBrick Devices): BBa_K1336007 for LacIEC+BsDyP+pSB1C3, and BBa_K1336006 for LacIEC+ispB+pSB1C3. This latter ispB asDNA device has functions in the biosafety aspects of our ARC.
