Mycobacterial interspersed repetitive unit (MIRU) of two Mycobacterium tuberculosis clinical isolates; in this method several loci where variable numbers of tandem repeats are chosen for replication using PCR. The locus number is shown on the top of each lane. Source: Reproduced, with permission, from Kanduma et al. (2003). FIGURE 6.2

©2011 Elsevier, Inc. The pap locus of uropathogenic Escherichia coli contains three genes: PapI, PapA, and PapB, and binding sites for the leucine responsive regulatory protein, GATC. When one GATC site is methylated (ME) by Dam methylase, PapI, PapB, and PapA are expressed; when the other is methylated, they are not expressed.
