Alignment of the tra genes of pG8786 (lower diagram) with the tra genes of the pED208 plasmid from S. enterica serovar Typhi (upper diagram). The solid arrows represent ORFs which are equally represented in the two plasmids. The open arrows represent ORFs which are absent in either of the two transfer regions. IS285*, IS285 insertion sequence which appeared to be a nonfunctional remnant. The vertical lines between arrows indicate similar ORFs.
