Comments
The IR of ISAzvi12 are not at its termini. In the IS sequence, as given, 7nt separate IRl from the left-hand end of the element and 3nt separates IRr from the right-hand end. Like other IS1111 family, ISKpn4 subgroup members, ISAzvi12 targets a specific site in the 59be (or attC sites) in gene cassettes associated with integrons and is inserted in only one orientation.
ISAzvi12 is 79% aa similar to ISKpn4.
