Q1: Infrared Emitting Protein

  • I've found parts that cantranslate green, yellow, and red fluorescence protein, but I can't find that can emit infrared rays. Can anyone help me find it? (posted by De-Ming Lin)
    • I am not sure there is a one can emit infrared light.
  • What is your original idea for having the special part?
    • If we can combine glucose promoter and structural gene which can translate protein that can emit infrared ray, and put it on the finger tip, we can measure blood sugar by an non-invasive way.
    • I think it is the question about how to measure the promoter activity under glucose stimulus in our system (8/30).

Q2: Documentation of Projects

  • For documentation, please all create a page for each of the five candidate projects on "My hot teams" and describe your design there. Uploading all the files of powerpoint or reference literature is very welcome! Thank you all very much for efforts of documentation ^^ Can we just document the two selected projects?
    • Reply: I just want to make the "brainstorming" part of our documentation as lush as we can ^^" I know everybody is busy, so maybe some description words with some files already done (powerpoint and literature showed on 7/13) are plenty enough ^^
  • Should we have a good framework about how to record our experiments and ideas? (8/30)

Q3: Problems about Materials and Designs

  • 由於沒有材料，我們無法動手進行實驗; P200、P400 Promoter 序列.......也無法確定，要火速解決! (posted by 迪璿, partially solved)
    • design has been changed. There is no P200 or P400 promoters in our current planning.
  • Insulin gene的來源 (solved)
    • [http://www.dnai.org/text/mediashowcase/index2.html?id=329 A plasmid vector for expressing the human insulin gene in nonendocrine cells, 1994]
    • A method for cloning the insulin gene from total human DNA is developed on the basis of the polymerase chain reaction. Cloning of the insulin gene from the total DNA of human lymphocytes is performed to obtain a pNP-90 vector for subsequent expression of the insulin gene in nonendocrine cells for the purposes of gene therapy of diabetic angiopathies

  • How to transport insulin?
    • From the research of Japanese scientist, we have known that fusion proteins with an alpha-hemolysin (HlyA) C-terminal signal sequence are known to be secreted by the HlyB-HlyD-TolC translocator in Escherichia coli. And in their research, a particular mutant of hlyB and hlyD can achive higher transport efficiency. (The full article is [http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pubmed&pubmedid=15691914 here], and the source link in our site is [http://igem.ym.edu.tw/private_2007/index.php/Production_of_heterologous_proteins_in_Escherichia_coli here])
    • The twin arginine (Tat) secretion pathway allows the translocation of folded proteins across the cytoplasmic membrane of bacteria. Tat-specific signal peptides contain a characteristic amino acid motif ((S/T)RRXFLK) including two highly conserved consecutive arginine residues that are thought to be involved in the recognition of the signal peptides by the Tat translocase. (The full story can be found in [http://igem.ym.edu.tw/private_2007/index.php/Disulfide_bond_formation_in_Escherichia_coli here]. Source article is here and another article is [http://www.jbc.org/cgi/content/full/282/11/8309 here])
    • design of primers for constructing INS_A, INS_B, IDE with TAT signal peptides
  • How to activate insulin?
    • Owing to that insulin requires the di-sufur binding between chain A and B to activate its activity, and E.coli seldomly forms di-sufur bounds in the cytoplasma under highly reduced environment, the solution is to mutant glutathione oxidoreductase (gor) and/or thioredoxin reductase (trxB) genes to decrease the reducing power within the membrane. See also the [http://igem.ym.edu.tw/private_2007/index.php/Image:Disulfide_reducing.jpg di-sulfur reducing pathways]. The current solution is to buy E.coli with mutants on gene gor and trxB (find out the strain we need [http://wolfson.huji.ac.il/expression/Bacterial_Strains.htm#strains-exp here]). The full story can be found [http://igem.ym.edu.tw/private_2007/index.php/Disulfide_bond_formation_in_Escherichia_coli here] (Thanks for the sharing from Dr. Chang)
    • Besides, we made the insulin to be expressed separately in alpha and beta chains only instead of the full length
  • How to verify our insulin?
    • antibody of insulin
  • How to inhibit our insulin?
    • IDE (insulin degrdation enzyme)
  • How to prevent E.coli intakes the glucose?

Q13: Documentation

https://2007.igem.org/Jamboree/Compete#Online_Judging

    • Project Documentation on the iGEM Wiki

  • Description: The team's project should be documented on the iGEM 2007 wiki site with detail enough to replicate it independently. Additional presentational information about the team - their story, the rationale for the project, failures, successes, future work, etc. - is highly encouraged. Remember that these wiki pages will be the main source of inspiration for future teams, and having good documentation on them and in the part description in the registry increases the likelihood of more teams building on your project and your parts.
  • deadline: the iGEM wiki freezes 04:59 GMT Oct 27

    • Part Documentation on the Registry

  • Description: Document your parts well - the success of not just iGEM, but all of synthetic biology, depends on the development of well-characterized, reliable, standardized biological parts that have been designed to be simple to use and understand. The first step is complete documentation.
  • deadline: the Registry freezes 04:59 GMT Oct 27

 

Plan to document:

  • Regular meeting
  • My hot teams
  • Team schedule
  • Help me!
  • Protocols
  • Materials
  • Benchman
  • Our Part Registry 
  • Key experiments
  • Construct
  • Almost Depleted Reagents
  • You must know!
