4 (Figure 4) is a promoter-trap plasmid containing a promoterless aph gene and xylE gene, an E. coli rRNA transcriptional terminator upstream of the reporter genes, an oriM for plasmid replication in M. smegmatis , an oriE for plasmid replication in E. coli , and a hyg gene for selection in E. coli and M. smegmatis bacteria.
The genetic mobility assay was performed essentially as described in Guo et al ., 2000 (Figure 4) [ 25 ] . In brief, the donor plasmids (carrying the mutant or wild-type introns) were each co-transformed with a recipient plasmid pBRR3, carrying a promoterless tet R gene downstream of the target site (which are the ligated exons; positions -30/+15).
The basic I-TRAP approach (Figure 1) uses a genomic DNA library in a plasmid vector containing a promoterless 'operon' with two reporter genes.
The plasmid contains a unique Bam HI site upstream of the promoterless reporter operon for cloning of potential promoters.
2 is a promoter-trap plasmid containing a promoterless lacZ gene isolated from λgt11 in which the Eco RI site in the 3' end of the lacZ gene was removed by site-directed polymerase-chain-reaction (PCR) mutagenesis (personal communication R. Van Landingham).
