<p><b>L2</b></p>
 +
<p>The gene L2 encodes for a protein that is able to attach to silica. Taniguchi et al. reported in 2007 that the L2 ribosomal protein from <i>E. coli</i> strongly binds to silica surfaces, even up to 200 times tighter than poliarginine tags commonly used for protein purification. In their work, Taniguchi et al. (2007) constructed a fusion protein containing L2 and green fluorescent protein (GFP) which kept attached to a silica surface even after been washed for 24 hours with a buffer containing 1 M NaCl (<b>Figure 1</b>). <a href="https://2012.igem.org/Team:UANL_Mty-Mexico">UANL Mexico 2012</a> did not have this piece in stock, so we decided to synthetize L2 along with a peptide signal.</p>

<P><b>AIDA</b></p>
-
<tr>
+
<p>AIDA-I is an <i>E. coli</i> membrane protein with a passenger domain of 76 kDa exposed to the extracellular space and a transmembrane beta-barrel domain of 45 kDa; the latter has been used to express functional proteins in the cell-membrane of up to 65 kDa (van Bloois et al., 2011). Furthermore passengers coupled to AIDA-I have been reported to reach an expression level of more than 100,000 copies per cell in the outer membrane (Jose and Meyer, 2007). </p><center>

<td>
+
-
<p><i>E. coli</i> needs to resist saline environments, UV rays and temperature changes in order to capture Na+ ions, and produce an aroma as a reporter, everything in the water. But after <i>E. coli</i> performs its tasks, it is necessary to remove it from the water in order to obtain usable water; it was easy to do it through a biofilter.</p>
+
-
<p>We chose silica as the material for our biofilter, so that <i>E. coli</i> expressed a membrane protein which could have the ability for binding silica, and in that way remove <i>E. coli</i> from the water. This was possible for the circuit created by <a href="https://2012hs.igem.org/Team:CIDEB-UANL_Mexico">UANL Mexico 2012</a> team; they created a circuit to make <i>E. coli</i> attached to silica, but as they did not proved it, we want to determine if it really works or not.</p>

<br><p><b>How is the Union module composed?</b></p>

-
<p>The binding circuit consists mainly in a fusion protein (a set which includes the CDS L2 with its peptide signal and AIDA) in order to make the protein for binding silica, a membrane protein. In that way <i>E. coli</i> would attach to silica.</p>

<p><b>How do L2 and AIDA act together?</b></p>
-
align=center hspace=12 alt="IMG_0317"></p></center>
+
<p>As AIDA is a membrane protein producer and L2 produces a protein for making possible the attachment to silica, the team decided to make a fusion protein, so that the protein produced by L2 can be translocated to the membrane of the bacteria with the help of AIDA, and in that way, binding the E.CARU to silica pearls for being filtered.</p>
-
<center><p><b>Figure 1.</b> Union circuit</p></center>
+
<p><b>Why is it important to use BgIII and BamHI to link L2 and AIDA-I?</b></p>
-
<br><p><b>How does L2 and AIDA act together?</b></p>
+
<p>It was needed to join both proteins in order to make a fusion protein, but SpeI and XbaI could not be used to join them because the reading frame would change, coding for a completely different protein. In order to avoid such problem, BgIII and BamHI were used instead, which could join AIDA and L2 without changing the reading frame. The scar produced between BamHI and BgIII, as it is shown in <b>Figure 3</b>, is formed by six bases, respecting the reading frame from both proteins in order to synthetize the correct protein.</p>

<p>The gene L2 encodes for a protein able to attach to silica. Taniguchi et al. reported in 2007 that the L2 ribosomal protein from <i>E. coli</i> strongly adsorbs to silica surfaces, up to 200 times tighter than poliarginine tags commonly used for protein purification. In their work, Taniguchiet al. 2007, constructed a fusion protein of L2 and green fluorescent protein (GFP) which adsorbed to a silica surface even after washing for 24 hours with a buffer containing 1 M NaCl (<b>Figure 2</b>). <a href="https://2012hs.igem.org/Team:CIDEB-UANL_Mexico">UANL Mexico 2012</a> did not have this piece in stock, so we decided to synthetize L2.</p>

<p>Initially, L2+AIDA and IrrE, protein for giving resistance to <i>E. coli</i> to adverse conditions (<a href="https://2014hs.igem.org/Team:CIDEB-UANL_Mexico/project_resistance">Resistance module</a>), were joined together in only one circuit, but we needed to separate them because L2+AIDA has not been tested and it could affect the production of IrrE (see <b>Figure 4.</b>) as well as for testing each module alone.</p>

<p>AIDA-I is an <i>E. coli</i> membrane protein with a passenger domain of 76 kDa exposed to the extracellular space and a transmembrane beta-barrel domain of 45 kDa; the latter has been used to express functional proteins in the cell-membrane of up to 65 kDa (van Bloois et al., 2011). Furthermore passengers coupled to AIDA-I have been reported to reach an expression level of more than 100,000 copies per cell in the outer membrane (Jose and Meyer, 2007). AIDA-1 allows the expression of proteins larger than small peptides in the outer membrane what makes it the best option to use with L2. AIDA-I was obtained by PCR for <a href="https://2012hs.igem.org/Team:CIDEB-UANL_Mexico">UANL Mexico 2012</a>, so we use their piece for our project.</p>

<p>The union circuit consists mainly of a constitutive promoter, an RBS, a peptide signal attached to L2 and this attached to AIDA by a scar and a terminator. The device is designed this way in order to produce a protein that helps the bacteria to bind to silica.</p>

<p>As we need to join both proteins in order to make a fusion protein we cannot use SpeI and XbaI to join them because the reading frame would change making a completely different protein. So in order to avoid such problem we use BgIII and BamHI instead which can join AIDA and L2 without changing the reading frame. The scar produced between BamHI and BgIII, as is shown in the figure 2, is formed by six bases respecting the reading frame from both proteins in order to synthetize the correct protein.</p><br>

<p>We will use a silica biofilter to remove <i>E. coli</i> from water, but in order to observe if really <i>E. coli</i> would attach to it we wanted to use a Wintergreen aroma as reporter. This would lead us know if the bacteria are in the biofilter by adding salicylic acid and changing the temperature; but as we will test this module alone we needed to design a new way to observe if L2+AIDA works. We decided to transform <i>E. coli</i> with two plasmids, one with RFP and the other containing the fusion protein (<b>figure 6</b>); if the biofilter becomes red it would mean <i>E. coli</i> is attached to it.</p>

<p>Silica was chosen as the ideal material because it is cheap and it is commonly found and also because the team wanted to give this material a new use. It was also chosen in order to finish the <a href="https://2012.igem.org/Team:UANL_Mty-Mexico">UANL Mexico 2012</a> team work.

<p>AIDA-1 allows the expression of proteins larger than small peptides in the outer membrane, which is why it is the best option to use with L2.

iGEM CIDEB 2014 - Project

Union Module

After E.CARU performs its other tasks, in order to remove E. coli from the salty water for making it useful, the ability for binding to silica was introduced to the bacteria. Using this ability, it would be easy to clean the water free of bacterium through a biological filter.

Description

L2

The gene L2 encodes for a protein that is able to attach to silica. Taniguchi et al. reported in 2007 that the L2 ribosomal protein from E. coli strongly binds to silica surfaces, even up to 200 times tighter than poliarginine tags commonly used for protein purification. In their work, Taniguchi et al. (2007) constructed a fusion protein containing L2 and green fluorescent protein (GFP) which kept attached to a silica surface even after been washed for 24 hours with a buffer containing 1 M NaCl (Figure 1). UANL Mexico 2012 did not have this piece in stock, so we decided to synthetize L2 along with a peptide signal.

AIDA

AIDA-I is an E. coli membrane protein with a passenger domain of 76 kDa exposed to the extracellular space and a transmembrane beta-barrel domain of 45 kDa; the latter has been used to express functional proteins in the cell-membrane of up to 65 kDa (van Bloois et al., 2011). Furthermore passengers coupled to AIDA-I have been reported to reach an expression level of more than 100,000 copies per cell in the outer membrane (Jose and Meyer, 2007).

Figure 2. Schematic representation of AIDA-I carrier protein


How do L2 and AIDA act together?

As AIDA is a membrane protein producer and L2 produces a protein for making possible the attachment to silica, the team decided to make a fusion protein, so that the protein produced by L2 can be translocated to the membrane of the bacteria with the help of AIDA, and in that way, binding the E.CARU to silica pearls for being filtered.

Why is it important to use BgIII and BamHI to link L2 and AIDA-I?

It was needed to join both proteins in order to make a fusion protein, but SpeI and XbaI could not be used to join them because the reading frame would change, coding for a completely different protein. In order to avoid such problem, BgIII and BamHI were used instead, which could join AIDA and L2 without changing the reading frame. The scar produced between BamHI and BgIII, as it is shown in Figure 3, is formed by six bases, respecting the reading frame from both proteins in order to synthetize the correct protein.

Device

Initially, L2+AIDA and IrrE, protein for giving resistance to E. coli to adverse conditions (Resistance module), were joined together in only one circuit, but we needed to separate them because L2+AIDA has not been tested and it could affect the production of IrrE (see Figure 4.) as well as for testing each module alone.

Figure 4. Circuit for our project and for testing resistance and union modules.


The union circuit consists mainly of a constitutive promoter, an RBS, a peptide signal attached to L2 and this attached to AIDA by a scar and a terminator. The device is designed this way in order to produce a protein that helps the bacteria to bind to silica.

CODE

DESCRIPTION

BBa_J23119

The J23119 is the most effective and common constitutive promoter used. It has a length of 35bp.

BBa­_B0034

This specific RBS is based on Elowitz repressilator. It has a length of 12bp.

BBa_K888000

L2. This CDS gives the property for binding silica and glass surfaces to E. coli, it has a length of 819 bp.

BBa_K888001

AIDA-I is synthetized as a 132 kDa pre-protein featuring a signal peptide which is cleaved during transport trough the inner membrane, a 78 kDa adhesin (passenger) domain, and a 45 kDa translocator. This autotransporter has a large capability in translocating relatively large passengers from 12-65 kDa by showing a N-terminal type of fusion. Coupled with a passenger domain and a signal peptide (K888005), it is possible to express functional proteins in the outer membrane of E. coli. It has a length of 1482 bp.

 

BBa_K888005

When this part is coupled with a passenger attached to AIDA-I translocator domain (K888001), it is possible to express functional proteins in the outer membrane of E. coli. The signal peptide is naturally cleaved during transport trough the inner membrane (Li et al. 2007; van Bloois et al. 2011).It has a length of 147 bp.

Part made of 6bp, responsible for stopping transcription.


Justifications

Although E. coli could acquire the ability to bind to silica, a biological filter was designed to remove bacteria from water. The team´s proposed biofilter is shown next:

Figure 6. The team's proposed biofilter model

Silica was chosen as the ideal material because it is cheap and it is commonly found and also because the team wanted to give this material a new use. It was also chosen in order to finish the UANL Mexico 2012 team work. They created a circuit to make E. coli bind to silica, but as they did not prove it, we wanted to determine if it is functional.

AIDA-1 allows the expression of proteins larger than small peptides in the outer membrane, which is why it is the best option to use with L2. AIDA-I was obtained by PCR by UANL Mexico 2012, so we decided use their piece for our project, as it was easy for the team to obtain it because both of the teams are in the same city.

Other teams that used it

UANL México 2012: They proposed the fusion protein for using it to binding silica after detect and capture arsenic acid in groundwater, and in that way removed the pollutant arsenic acid from the water, as part of water bioremediation. However, their project was not finished.
