Personal Objectives

Uriel Urquiza

• • Construction of the phage production control system.

  In order to produce a grate amount of P4 phage particles that has our death system, we want to avoid the natural
  early lysis that occur when WT P4 and P2 interact. This avoidance will be achieved by taking the control of the two
  major regulators of P2 morphopoietic genes. The control systems that is going to be implemented is constituted by a 
  promoter inducible by IPTG () in conjunction with transactivators cox and ogr from phage P2. All this will allow 
  us to grow bacteria in grate quantities and induce lysis when ever we want and as a consequence obtation of grate
  amounts of P4 phage.

• • Qualitative characterization of multipromter.

Laura Gomez

• • To obtain all the relevant experimental information about T7 and T3.

 Model validation needs some critical parameters like strain(C1a) growth rate and the T3 and T7 burst sizes. The 
 parameters found in the literature correspond to k12 strain however we used a k12 derivative strain, C1a, for this 
 reason it was indispensable to obtain experimentally a C1a growth plot. In the same way, simulations
 showed us that the burst size is a critical parameter to determine the efficiency of our system.

• • Generation of data to feedback the infection model.

 The experimental data would be used to feedback the model in order to obtain the most accurate model as possible.

Abraham Avelar

• • Ensamble the kamikaze construction

 Clone the colicines with the multipromoter. 
 Design and Clone the asRNA.
 Help in the ensamble of all the device.

• • Test the construction

 Obtain the time that E3 takes to kill E. coli, this parameter will be provided to the model. The preference 
for E3 above E9 is due to a modeling suggestion that shows the effectivity of our system when the translation
 machinery is disrupted
 Test the efficience of plaquing with the asRNA by itself
 Test the efficience of all the device.

1) I'm in charge of the assembly of the P4 vector.

• I must create an eternal bacterial source of P4 sid1. Therefore I must Infect C1a with it.
• I need to develop a good protocol for P4 sid1 lysate production.
• I must obtain the essential region of P4 sid 1 by pcr. This will add preffix and suffix to the region.
  

3) I need to ligate the "biobricked" P4 region to a reporter; better off RFP or a hard-resistance antibiotic. Then, I have to transform to produce P4 (preferably with our stock producing bacterium) and infect wild-type strains to look for reporter associated colonies. (Also try in many bacterial strains)
4) When the kamikaze system is ready, I need to ligate the P4sid1 region to it and transform an E.coli C1a strain with it.
5) then we can start testing the system!
6) ultimate goal: standardize P4 as an iGEM vector

Enrique Paz

• • Desingn of our modified version of bacteriophage P4

 What we need to do over P4 genome and how 

to do it in order to construct a bacteriophage compatible with standards in synthetic biology.

• • Construction and test of the alarm device (quorum sensing)

 Some -a lot- restrictions, ligations,
transformations, tests, etc. To achieve a high quality device for quorum sensing that we will use for construction of our "alarm" system.

• • Test the host range of our modified P4

 According to litterature bacteriophage P4 has
an unusual host-range. We would like to test it so we can transport easily synthetic construction to another interesting bacteria species!
