Genetic maps of putative prophages detected in the C. ulcerans genomes. The functional annotation of the prophage-like region ΦCULC809I from C. ulcerans 809 and of the prophage-like regions ΦCULC22I, ΦCULC22II, ΦCULC22III, and ΦCULC22IV from C. ulcerans BR-AD22 is shown. The predicted protein functions are indicated by color codes. ΦCULC809I and ΦCULC22I are closely related genetic elements according to the very high overall similarity of their genes and gene products. The nucleotide sequences of putative integration sites of ΦCULC22II, ΦCULC22III, and ΦCULC22IV in the chromosome of C. ulcerans BR-AD22 are shown. tRNA genes flanking the putative prophages are indicated as blue triangles.
