Plan

Aim: Create bacteria that produce a noxious odour when induced to do so
Methods:

Clone the yqiT gene from Bacillus subtilis into a biobrick vector.
Make constructs that express this gene constitutively and under the control of an inducible promoter.

June

First, we haven't decided what promoter to use.
While looking for a good promoter, we were cloning YqiT and useful parts.

6/5

Constructs to be created:

yqiT
ptetR-RBS-yqiT-dterm
pAraC-RBS-yqiT-dterm
pLacI-RBS-yqiT-dterm

Obtaining DNA:

Resuspended DNA in the following wells with 10ul water:

Plate 1 1D
[http://partsregistry.org/wiki/index.php/Part:BBa_R0080 AraC regulated promoter] Plate 1 12E
[http://partsregistry.org/wiki/index.php?title=Part:BBa_R0010 LacI regulated promoter]

Plate 1 1H
[http://partsregistry.org/wiki/index.php/Part:BBa_B0030 Strong RBS]

Plate 1 13B
[http://partsregistry.org/wiki/index.php?title=Part:BBa_J13002 TetR repressed POPS generator]

Plate 2 24C
[http://partsregistry.org/wiki/index.php?title=Part:BBa_B0014 Double terminator]

Transformed 1ul of each of the above into DH5a competent cells:

Transformation

Mix 1ul of DNA with 100ul of competent cells on ice.
Leave on ice for 30 minutes.
Heat shock at 42°Cfor 45 seconds.
Leave on ice for 2 minutes.
Add 500ul of LB and incubate at 37°C for 1 hour.
Plate on LB-ampicillin plates.

6/6

No colonies grew from the 5 transformations of 6/5.

6/7

Creating a biobrick part out of yqiT

Strategy: PCR out the yqiT gene from the Bacillus subtilis genome using primers to attach the biobrick preffix/suffix and clone this into a biobrick vector. The vector utilized is the GFP generator which houses a sufficient-sized insert:

Plate 1 16E (from 2007 iGEM distribution provided by Chiba University)
[http://partsregistry.org/wiki/index.php?title=Part:BBa_E0840 GFP generator]

Overview:

PCR yqiT gene from genome
purify DNA from the PCR product
digest GFP generator and purified PCR product by XbaI/PstI
gel-purify the digested vector (GFP generator without the insert i.e. empty) and the yqiT gene
ligate the above 2 fragments of DNA together
transform into E. coli and select for ampicillin resistance
check for transformation success using colony PCR by yqiT primers

PCR of yqiT gene
The Bacillus subtilis genome was provided by Bacillus subtilis 168

The following primers were used to amplify an approx. 1500bp fragment from the Bacillus subtilis genome.

3. 50°C 30 seconds
4. 72°C 40 seconds
5. Repeat 2-4 23 times
6. 25°C forever

Purified PCR product using the Promega PCR purification kit.

Ran on gel to visualize bands:

PCR unsuccessful: will digest the GFP generator but cannot perform the ligation without the PCR product.

Digestion
Digested purified PCR product and the GFP generator both with XbaI/PstI:

GFP generator
6ul DNA
2ul High buffer

Cut out the second band from the bottom and dissolved the gel using the Promega gel purification kit to extract DNA from.

This DNA is stored for later usage as the GFP generator X/P vector fragment.
