Schematic map of TnSha2 elements. The circular maps of the prototype 11.7 kb plasmid sequence of TnSha2 (S. aureus strain M0227, GenBank accession JCAZ01000023) and the target 8.7 kb TnSha1-free plasmid (S. haemolyticus CUCL01000044 or S. aureus JJAQ010000025) are shown in panel (A). The map of TnSha2 integrated into the S. haemolyticus chromosome at a position occupied by a single IS1272 in the reference strain is shown in panel (B). In three occasions the resulting chromosomal island is bordered by two IS1272 elements (CUCK01000025 at position 590129 of strain JCSC1435, CUDY01000029 at 1828271, and CUGD01000039 at 2443315) wile in one case only by the “left” IS1272 element (CUDB01000007 at 1322312). Comparison between pTnSha2 element (S. aureus JCAZ01000023) and pSE-12228-03 (S. epidermidis NC_005006) is shown in panel (C). Numbers between brackets indicate coverage percentage and identity percentage respectively. The genes encode for: a putative DNA-directed DNA polymerase (DNA pol), a replication protein involved in a theta-type replication mechanism (Rep), a putative mobilization protein (Mob), a domain of a group of polymorphic toxin proteins (LXG), a Site-specific DNA recombinase related to the DNA invertase Pin (PinE), and a conjugal transfer pilin chaperone (TraQ).
