+ | <h2>Diary: Week 1</h2> | ||
+ | <p>During week 1 the team decided on a rough project outline which involves producing a protein microcompartment found in Salmonella in E.coli. Bacterial microcompartments (BMC’s) are protein organelles found within bacteria. The physiological function of these compartments is to promote specific metabolic processes by colocalising enzymes with subtrates and also cofactors. After expressing the microcompartment in E.coli we will attempt to target different proteins to the compartment which may have a bioremediation function for example. Ideas on what could be targeted to the compartment as well as a name for the project are still under discussion.</p> | ||
+ | |||
+ | <p>The team was given a health and safety briefing and before starting in the labs attended a several tutorials on basic microbiology and molecular biology. The rest of the week was spent learning different laboratory techniques such as miniprep, transformations, isolating chromosomal DNA, PCR and restriction digests which will be critical for our project. Although this was largely successful some of the team did not get the desired result from their PCR’s (Jane and Brian) better luck next time. Towards the end of the week we had a group meeting and discussion to establish a cloning strategy and also to design the primers needed for our gene of interest. Our computer team spent a large amount of the week designing our website which is now up and running.</p> | ||

A restriction digest was then performed as well as adding an Antarctic phosphatase to prevent our plasmids rejoining. Our plasmids are now ready to be incorporated with our genes of interest.

As well as this the team began to work on the targeting sequence of the protein PduD. It is known that PduD contains a 40 amino acid signal sequence which is necessary to incorporate proteins into the microcomparment. As well as using a 40 amino acid sequence we are also going to attempt to use a 20 amino acid sequence.

The plan is use the microcompartment to produce lemonade, using limonene and aspartate biobricks from the iGEM directory.

Possible Project Ideas
Diary: Week 1
During week 1 the team decided on a rough project outline which involves producing a protein microcompartment found in Salmonella in E.coli. Bacterial microcompartments (BMC’s) are protein organelles found within bacteria. The physiological function of these compartments is to promote specific metabolic processes by colocalising enzymes with subtrates and also cofactors. After expressing the microcompartment in E.coli we will attempt to target different proteins to the compartment which may have a bioremediation function for example. Ideas on what could be targeted to the compartment as well as a name for the project are still under discussion.
The team was given a health and safety briefing and before starting in the labs attended a several tutorials on basic microbiology and molecular biology. The rest of the week was spent learning different laboratory techniques such as miniprep, transformations, isolating chromosomal DNA, PCR and restriction digests which will be critical for our project. Although this was largely successful some of the team did not get the desired result from their PCR’s (Jane and Brian) better luck next time. Towards the end of the week we had a group meeting and discussion to establish a cloning strategy and also to design the primers needed for our gene of interest. Our computer team spent a large amount of the week designing our website which is now up and running.
Fail of the Week = Jane’s PCR
Diary: Week 2
Week 2 saw the team begin the iGEM project. It began by performing mini-preps to extract the plasmid pUNI-PROM from our E.coli strain. A restriction digest was then performed as well as adding an Antarctic phosphatase to prevent our plasmids rejoining. Our plasmids are now ready to be incorporated with our genes of interest. While waiting for the primers to arrive our team divided into groups to work on a project outline and description as well as the health and safety issues of the project.
Primers finally arrived. PCR’s were performed and our genes of interest were successfully incorporated into our vector through ligation and stratoclean steps. Our clones were left to grow in LB Amp medium so that we can perform Quick change on the genes which have additional Pst I sites on them.

The final push is on. Work is still under way to complete the microcompartment as well as individual projects.

The microcompartment is getting very close to completion we have now successfully cloned ABTUN into our plasmid and hopefully we will have JK into the plasmid at the end of the week.

Diary: Week 9
The seven genes which encode the bacterial microcompartment have successfully all been cloned into E.coli and have been fully sequenced. The focus of this week was to make all our bacteria with the various targeting proteins such as GFP/mCherry and ferrtin competent so that they may be transformed with plasmids which have the microcompartment genes.
On Sunday we took part in our discussion along with the iGEM team from St Andrews with participants from the World Debating Competition. This event was a great success with some excellent input from all that took part. Videos will be available soon. Towards the end of the week we all went out on group outing termed the ‘Last Supper’ to a local Italian restaurant which serves the best Italian around many thanks to our supervisor Frank Sargent for taking us there.
Diary: Week 10
The final week of iGEM is upon us. The majority of this week was spent performing Western Blotts and protein purifications as well some 35S radioactive labelling experiments which have provided some very interesting results which will be spoken about in Amsterdam. iGEM has been a brilliant experience and I think I speak for the whole team when I say it is something that if you have the opportunity to do you should definitely take part. The competition provides a great deal of lab experience something which is much sought after but also allows you to take part in a new and very exciting field of biology.
