Cyanobacteria is not optimal system to manipulate the protein expression mainly due of the lack of strong promoters. Pcpc560 is a Cyanobacterial super promoter discovered by Dr. Ma’s team that contains two predicted promoters 14 predicted transcription binding site.  Using the Pcpc560, Dr. Ma’s team demonstrated that functional protein were produced at 15% of the total protein production. Our team decided to test the effect protein production in E.Coli cells DH5α using the 14 predicted transcription binding site from Pcpc560. We believe that 14 sequential binding sites from Pcpc560 will allow us to increase the protein function production greatly using the E.Coli DH5α. We have constructed the 14 transcription binding followed by an strong RBS (BBa_B0030), followed by mutant HIS-Tag psbB. The super promoter can be an valuable asset to other iGEM teams for protein production and therefore we have decided to submit the Construct along with 14 Transcription binding site from Pcpc560.

BBa_K2127002 (psbB): http://parts.igem.org/Part:BBa_K2127002

The psbB gene codes for the CP-47 subunit of the Cyanobacterial Photosystem II in Synechocystis sp. PCC 6803. Using site-directed Mutagenesis Dr Frankel’s team developed a Synechocystis sp. PCC 6803 mutant containing a histidine tag at the C-Terminus of CP47 subunit. Using the His-Tag we isolated the Photosystem II complex and analyzed the activity using the electron evolution analyzer. Photosystem II purification with high activity highlighted that CP-47 with HIS-Tag at C-terminus can made into BioBricks. We are submitting psbB gene as a BioBrick to claim Silver Medal.

BBa_K2127003 (psbT-like): http://parts.igem.org/Part:BBa_K2127003

The psbT subunit of the Photosystem II in Synechocystis sp. PCC 6803 is a single membrane-spanning a-Helix of ~3.5 kDa with C-Terminus located on the stromal side of the Thylakoid Membrane. Structural studies of psbT Studies have showing that removal of the psbT subunit reduces the rate of electron transfer between the QA and QB and less resistance to photo-damage. It is an integral part of the Cyanobacterial photosystem II complex and it plays an important role in the electron transfer. For iGEM 2016, our team decided to submit the psbT gene as a BioBrick due to Photosystem II being an integral part of our project. We are calming Bronze medal for this BioBrick.
