This is the iteration plan for the Construction iteration(s). See [http://www.upedu.org/upedu/process/artifact/ar_itpln.htm the UPEDU artifact description] for information on what this is and what it contains (including a template).

Milestone

These are the major [http://www.upedu.org/upedu/process/itrwkfls/ms_ioc.htm milestone objectives] for the Construction phase:

• TODO Our wonderful buoyant, metal filtering bacteria should be alive and kicking!
• TODO (?) The lab/plan cloning strategy should be fully worked out at the end of the phase to reflect our final decisions on which parts/protocols/procedures/? to use. (I think this roughly corresponds to the Implementation Model in UPEDU. --Jaspervdg 11:09, 23 June 2009 (UTC))
• TODO The Iteration plan for the transition phase completed and reviewed.
• TODO (?) Design Model (and all constituent artifacts) updated with new design elements identified during the completion of all requirements. (I think this can roughly be seen as fleshing out all the device designs and parts, or in other words: making sure The Project is up-to-date. --Jaspervdg 11:09, 23 June 2009 (UTC))
• TODO More?

Resources

Note that we're opting to do this for the entire phase instead of each iteration as in UPEDU as this seems more natural (our needs change little over the course of one phase). --Jaspervdg 11:01, 23 June 2009 (UTC)

[Resources needed for the phase — material, human, financial, and so on.]

Construction 1

Overall objective:

• The basic model should be ready
• The seperate part of the labwork should be known and working or almost working
• modellers should know which parameters they need so the labworkers can prepare providing these
• The tickets and hostel should be booked

Week 27

June 30 - July 5 :

• Analyst
• Configuration Manager
• Designer
• Implementer
  • Have genes as BioBricks in the vector, together with all DNA elements needed for expression (RBS, term etc).
  • Work on the final parts should have been started.
  • Try to find protocols for the characterization, to check feasibility.
  • Keep record of the labwork on the Notebook site
  • GVP (Michael and Paul)
    1. Test insert length of gvp cluster (E-genR-X-RBS-PART-S-P in vector , Figure 1)
    2. (Needed?) Silence restrictionsites in gvp cluster by PCR (BamHI, XhoI, BglII --> used in other BBa standard assemblies)and remove repeat in gvpL.
    3. Add the terminator to the construct
    4. If needed add promoter (constitutive promoter --> ) to do initial phenotype testing.
  • Metal transporters (Jolanda, SJ)
    1. Transform E. coli with construct (HmtA first, get GlpF either by ordering or by genome PCR. Then order primers + pre/suffix and RBS in prefix).
    2. Test insert length.
    3. Silence restrictionsites in HtmA by PCR (2x PstI) and add BioBrick pre/suffix.
    4. Clone the terminator in to the construct.
  • Metal accumulation (Wilfred, Nienke)
    1. Decide which Metallothioneins will be used.
    2. Transform E. coli with construct / synthetic gene.
    3. Test insert length.
    4. (If needed) Silence restrictionsites in gvp cluster by PCR.
    5. Add BioBrick pre/suffix by PCR.
    6. Clone the terminator in to the construct.
  • Vectors (Sven, Frans (Modelling aswell?)):
    1. Transform E. coli TOP10 with pSB3K3 and E. coli DB3.1 with pSB1AC3.
       1. pSB3K3 contains a p15A ORI and Kan resistance.
       2. pSB1AC3 contains Amp + Cam resistance markers, a ccdB death gene and a pMB1 ORI.
    2. Add different promoters to the vectors:
       1. Inducible are: pBAD-AraC in pSB2K3 and the Lac promoter in pSB1A2.
       2. Constitutive are: High expected expression yield, and Low expected expression yield, Lac promoter with mutated operator . For these promoter sequences are too small, oligo's have to be ordered + BBa pre/suffix !!without RBS!!
       3. Metal sentitive are possibly copA (order oligo's) and ??
          1. Clone in such a way that they are nicely -10 / -30 in front of the start codon.
    3. Test functionality of the promoters by cloning GFP + RBS + Terminator behind the promoter (BioBrick??).
• Integrator
• Modeller
• Project Manager
  • Have both modellers and labworkers up and running.
  • Labworkers have choosen the parts and tested those. The bouyancy, metal intake and accumulation should be tested and working seperatly.
  • Have a start-up model and make sure the labworkers know which parameters the modellers need and can or already have provided these.
  • Have choosen a tester, a "testplan" should have been made, the necessary equipment should be at least ordered.
  • the tickets and hostel should be booked, so plans for jamboree or thereafter should be known roughly.
• Public Relations Officer
  • Get in contact with papers, magazines and other media for possible publications.
  • Keep in contact with other teams on progress during the summer.

• Analyst
• Configuration Manager
• Designer
• Implementer
• Integrator
• Modeller
  • DONE Make a detailed list of things that should be measured in relation to buoyancy, indicating how well a guess we already have. For example (pretty much everything we'd love to have as a time series):

    • Volume fraction of gas vesicles (needs to be determined how best to estimate this), to check the relationship between the density of the rest of the cell and the presence of gas vesicles.

GVP (1pers):

The cutting and ligation was one of the more serious issues of Melbourne 2007 team, and might give us the same problems to keep in mind

    • Concentrations of bound metals vs. unbound metals in cells?
    • (Relative) promotor strengths? (We should be able to relate this to gvp/transporter expression in some way!)

    • DONE Find diffusion speed (if nonzero). (Most likely does not diffuse through the cell membrane.)
    • DONE What transporters in and out of the cell are there in our E. coli.
    • TODO How much transporters in and out of the cell are there in our E. coli.
