PlacIq-M13-Plac-GFP on pSB3

We confirmed that M13 genome with two modifications related to our design kept plaque forming activity. One is replacement of the promoter for g2p protein with a constitutive promoter, PlacIq (BBa_I14032). The other is accommodation of pSB3K3 backbone. Even though the plasmid has two different types of replication origins, M13 origin and pSB3 origin, this plasmid (BBa_K1139020) formed plaque. In contrast, construction intermediates without a promoter for g2p coding sequence (Promoterless-M13 + Plac, Promoterless-M13 + PlacGFP BBa_K1139022) could not form plaque.

 We confirmed that M13 genome with two modifications related to our design kept plaque forming activity.  One is replacement of the promoter for g2p protein with a constitutive promoter, PlacIq ([https://parts.igem.org/Part:BBa_I14032 BBa_I14032]).  The other is accommodation of pSB3K3 backbone. Even though the plasmid has two different types of replication origins, M13 origin and pSB3 origin, this plasmid ([https://parts.igem.org/Part:BBa_1139020 BBa_K1139020]) formed plaque.  In contrast, construction intermediates without a promoter for g2p coding sequence (Promoterless-M13 + Plac, Promoterless-M13 + PlacGFP [https://parts.igem.org/Part:BBa_1139022 BBa_K1139022]) could not form plaque.
