<p>The casette of degradation module (BBa_K1387006) is comprised of constitutive promoter, tet operator, RBS, outer membrane protein A (ompA) fused with LC Cutinase, and double terminator. By using constitutive promoter, we expect the recombinant protein, in this case ompA-LC Cutinase, will be synthesized indefinitely. OmpA is outer membrane protein, it comprises of β–strand B3-B7. Rather than using full sequence of ompA, we use ompA (46-159) fused with lipoprotein signal sequence, thus exposing it on the cell surface of bacteria1. We fuse lpp-ompA with LC Cutinase, an enzyme that exhibit esterase activity. LC-Cutinase esterase activity will cleave the ester bond on PET and releasing terephthalic acid and ethylene glycol as a product. Fusion strategy of lpp-ompA on LC Cutinase gene is one of our way to create a whole cell biocatalyst which will be an effective molecular machinery to degrade PET on the environment. Due to constitutive expression of the recombinant protein in E.coli, there is a possibility of formation of insoluble protein inside the cell (inclusion body), because of that, we put tet operator upstream of RBS for further regulation (Georgiou et al, 1996).</p>

SAFETY

  1. Have your team members received any safety training yet?

    2. Yes, we have already received safety training.


  2. Please briefly describe the topics that you learned about (or will learn about) in your safety training.

    3. - Safety Equipment

    - Waste Management

    - Recombinant DNA Technology and Biological Safety


  3. Please give a link to the laboratory safety training requirements of your institution (college, university, community lab, etc). Or, if you cannot give a link, briefly describe the requirements.

    4. Laboratory Assistant, College students and Technician


  4. Convertion Module

    5. Improvisation the part submitted by UC Davis team BBa_K936024 by combining the construct with terminator, so we can characterize the expression of the enzymes and performe the assay for ethylene glycol utilization better than before. We name this BioBrick as convertion module.


  5. References
