Characterization of IS1203, an insertion sequence in Escherichia coli O111:H-.
The complete nucleotide (nt) sequence of IS1203 from Escherichia coli O111:H- strain PH has been determined. IS1203 is 1312-nt long, with imperfect 26-bp terminal inverted repeats. The two major ORFs in IS1203 encode polypeptides of 12.7 and 33.7 kDa, the latter being the putative transposase. IS1203 is closely related to IS629 of Shigella sonnei and IS3411 of E. coli. At least twelve copies of IS1203 were found in the genome of E. coli O111:H- strain PH.
