ISL1: a new transposable element in Lactobacillus casei.
The genome structures of a temperate Lactobacillus phage, phi FSW, and its virulent mutants, phi FSVs, were examined by restriction, heteroduplex and nucleotide-sequence analyses. The results showed that two out of three phi FSVs had the same 1.3 kbp insertion (designated as ISL1) at different positions in the phi FSW sequence. ISL1 was 1,256 bp long and contained at least two long open reading frames of 279 and 822 bases on one strand. Inverted repeats were found at the termini of the ISL1 which was bracketed by 3 bp direct repeats of the phi FSW sequence. From this evidence, we concluded that ISL1 was a transposable element in Lactobacillus casei.
