In-frame deletions were made in the Exc operon contained on pGRW53 and the resultant constructs were tested for their abilities to induce activity of the Ptra ::uidA fusion pGW40.5 in the Bacteroides host, BT4001ΩQABC. The GUS activity was measured when the strains were grown with and without tetracycline. The range of the tetracycline induced GUS activities for each isolate relative to the pHopp1 is seen on the right of the schematic for each construct tested. The schematics depict the genes on pGRW53 and then the in-frame deletions of the gene being tested. Plasmids containing deletions in the orf3 gene had no phenotype in these experiments.
