Week 1

Literary research:

We looked into SUMO protein, a protective group that we could use to stabilize the melittin peptide. We also looked into mechanisms to express or release melittin:

  • Using a signalling sequence, signal peptides and pathways (OmpA, SecB, IgA beta)in order to secrete melittin
  • Lysing our cells with a killswitch and then using FLAG tags, affinity tags to purify melittin from lysate
  • Proteases to cleave off a protecting group.

We also looked into understanding biobricking assembly standards

Week 2

Literary research:

  • Prepromelittin nucleotide sequence was found.
  • Decided on a fusion protein with melittin and GST tag
  • Reached out to Genomics Core Facility on Stony Brook University Campus to talk with Dr. John Schwedes about RNA extraction and Dr. Dmitri Gnatenko about primer design.
  • Searching for plasmids: met with Yelena from Molecular Cloning Facility to discuss appropriate plasmids for our experiment and search through their plasmid library

Experimental:

  • Competent E.coli cell line made.
  • Visited local beehive to obtain Apis mellifera samples; dissected our bees and extracted their RNA
  • Transformed RhlR biobrick

Outreach:

We presented on synthetic biology at four classes at a local high school, East Sachem High School!

Week 3

Literary research:

  • Looking into P. syringae as a model for P. aeruginosa?
  • Optimal expression conditions
  • Looking into TEV protease site to cleave off GST protein
  • Detection methods

Experimental:

  • Designed primers for melittin amplification and tagged melittin
  • Successful RNA extraction!
  • Obtained plasmid from our advisor, Dr. Czaplinski
  • Designed RhlR circuit and obtained signaling compound C4HSL
  • Constitutive promoter BBa_J23101 and J23102 transformed for later fluorescence testing

Week 4

Experimental:

  • Synthesized cDNA library
  • Designed and ordered Biobrick melittin primers
  • mCherry and fluorescence testing

Outreach:

  • Looked into doing an iGEM survey with other schools with the Stony Brook Institutional Review Board
  • Attended iGEM High School Jamboree!


Week 1

Experimental:

  • Ligated and transformed for GST-melittin fusion protein
  • Induced plasmid with IPTG and checked with SDS page gel- no protein detected
  • Redid PCR and digest
  • Sequenced RhlR/Rhl circuit samples

Week 2

Experimental:

  • Prepared insert for our melittin plasmid- used PCR to amplify melittin, insert TEV cleavage site, then digested insert, and purified
  • Digested RhlR/ rhl plasmid, phosphatased, purified, ligated, and transformed. Cultured overnight, miniprepped and ran on gel to check results.
  • RhlR + Promoter miniprep, sent for sequencing

Outreach

Presentated at Stony Brook University Biotechnology Camp for high school students!

Week 3

Experimental:

  • Digest check, sequencing results for RhlR/Rhl
  • Screened colonies for melittin
