Isolation and characterization of IS1181, an insertion sequence from Staphylococcus aureus.
The repeated nucleotide sequence isolated from a methicillin-resistant Staphylococcus aureus isolate displays the characteristic features of an insertion sequence and was named IS1181. It has a size of 1512 bp and consists of a 1359-bp open reading frame that encodes a 439-amino-acid protein which is predicted to be highly basic and 23-bp terminal inverted complementary repeated sequences exhibiting six mismatches. The three copies of IS1181 isolated from distinct parts of the chromosome of S. aureus, BM3121, are flanked at their ends by 8-bp direct repeats, suggesting a duplication of the target sequence. IS1181 exhibits similarities with IS1165 from Leuconostoc mesenteroides and IS1001 from Bordetella parapertusis. IS1181 was detected in at least two to eight copies in 41 of the 52 S. aureus isolates tested, whereas none of the 26 coagulase-negative staphylococci, 24 streptococci, or 11 enterococci analyzed carried nucleotide sequences hybridizing with IS1181.
