Shown below is pGULIG-12. Note the following genetic elements: At the top of the map is the origin of replication of the ColE1 plasmid. Note that the rna-II is expressed from the trp promoter. Note that the trp promoter is not followed by any trp protein coding sequences. Moving clockwise: From 1:00-3:00 are the genes for the coding sequences for the two components of a typical two partner secretion system. The β barrel protein and passenger protein genes are indicated. Both of these genes are expressed by the promoter for the araBAD genes. From 4:00-5:00 is the tet gene expressed by the λ pR promoter. From 6:00-8:00 is the pir gene expressed from the dnaK promoter. From 8:00-10:00 is the λ CI gene expressed from the lac promoter. There are no other promoters on this plasmid other than those indicated on the map. Assume that all genes have appropriate translation start and stop codons. The short bars crossing the circle represent typical factor-independent terminators that will prevent transcriptional read through between these different elements. The host
