PlacIq-M13-Plac-GFP on pSB3

PlacIQ is a constitutive promoter. GFP expression is regulated by LacI repressor. 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.
