Helpers at SB6

Imperial SB.jpg



The BioBricks Foundation Synthetic Biology Conference Series (SBx.0 Conference) is the world’s foremost professional meeting in the field of synthetic biology. The BioBricks Foundation is the proud organizer of the conference series and this year Imperial had the honour of hosting the conference. SB6 ran 9th-11th July 2013. We were helpers at the conference, working behind the scenes to help delegates and in collaboration with the event organisers we ensured everything ran smoothly.

We were also lucky enough to see some great talks, and enjoyed networking amongst the synbio community! The buzz of SB6.0 gave us a boost and the inspiration for our iGEM project.




Presented at the YSB1.0 meeting

We presented at the very first Young Synthetic Biologists meeting at the Wellcome Trust. YSB1.0 was designed as an extension of the UK iGEM team meetup that has been organised in previous years. We had a great time and loved sharing our ideas, networking and having fun with the rest of the UK iGEM community. As an additional bonus, Randy Rettberg, one of the co-founders and current president of the iGEM foundation gave us an inspirational talk.

We met the team from St.Paul's School when we went to the Young Synthetic Biology event. We were impressed by their project of the previous year and got chatting to them. As school students they were keen to see some University Labs and discuss their project further so we invited them for a tour of the facilities at Imperial. We hope the tour was enjoyable and that the tips we gave them come in useful in their entry this year.







Yale: PLA-degradation

As soon as we found out Yale iGEM team was synthesizing poly lactic acid(PLA) this year, we contacted them and sent them our PLA degradation parts to test on their product. We did this to further characterise the part and see if Biobricks behave the same on both sides of the Atlantic! When Yale optimises PLA production, they will send some of their product to break down. Breaking down PLA is a second biological bioplastic recycling system we are working on, capable of producing the monomers required to chemically resynthesise it.

UCL:Beta-Amyloid Degradation

When we heard UCL's project was to degrade Beta-Amyloid plaques we were interested to see the results as degrading a substrate has a lot in common with our project. Beta-Amyloid is a component of Amyloid Plaques which are a pathological feature of Alzheimer's disease (AD), which UCL iGEM is targeting this year.It turns out that proteinase K is not only a good way to break PLA down, but also to degrade amyloid plaques. We were interested to see if our biobrick could be multi-functional so sent UCL a copy of it. We also built a degradation model to help the UCL team with their beta-amyloid degradation assays. The model, a MATLAB based extension called Simbiology, provides information about how efficient MMP-9 enzyme can degrade beta-amyloid plaques, which is informative for wetlab work.

Degradation Assays of UCL 2013 iGEM team

The details of the assays are here. There are three different substrates which are soluble aggregated β-amyloid (Aβ),aggregated β-amyloid (Aβ) fibrils 1-40 and aggregated β-amyloid (Aβ) fibrils 1-42. Here is the table that defines the initial concentrations of all substrates and the enzyme from the assays.

Species Concentration Units
soluble Aβ 25 uM
Aβ fibrils 1-40 200 uM
Aβ fibrils 1-42 100 uM
MMP-9 0.2 uM

Explanation

Equations

We choose simple Michalis-Menten mechanism for Beta-Amyloid degradation. The ODEs for all substrate are:

Simple MM.png

The Km values here are for each substrate correspondingly whereas Kcat values are for MMP-9 in each assay.

Assumption

Although Matrix metallopeptidase 9 (MMP-9) is a well characterised enzyme, there is no clear kinetic data for degrading soluble Beta-Amyloids and its fibrils.

We sent NRP-UEA Norwich iGEM team soil samples collected from London, in order for them to identify antimycin-producing bacteria inhabiting in the samples.

We transformed and sent for sequencing BioBrick parts BBa_C0061 and BBa_C0062 from our 2013 parts distribution. We were prepared to send the physical DNA to the team, however this became unnecessary since following our transformation advice the team was successful in obtaining the DNA from their own distribution.
