Comments
ISAjo3 is 97% aa (transposase) similar to ISAca1.
The third ORF is the putative ORFAB transposase reconstructed in silico by possible -1 frameshift.
ISAjo3 was found in the A. johnsonii GR13-type plasmid pXBB1-8. Copies flanked by 4 bp target site duplications were found in the chromosome of A. baumannii A388.
Additionnal accession number : CP079793, CP024418.
