Design Notes
This composite part is a derivative of BBa_K2127004 which is s coding sequence for a 47 kDa his-tagged subunit of the Photosystem II complex. The His-Tag was developed to isolate the Photosystem II complex and allow for no reduction in activity as measured by electron evolution. A double stop codon and a double terminator were introduced by our team to further ensure termination of transcription in vitro. To allow for easier ability for teams to work and analyze this subunit and its properties, the construct was designed to include an inducible lac promoter under LacI regulation.
When working with this BioBrick it is necessary for teams to ensure there replication host or vector contains a suitable lacI repressor gene.

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 designated mutant HT-3.
