Molecular structure of the 4341 bp circular form containing mosaic tet(S/M). Light grey identifies tet(S) ORF sequences in the mosaic gene, dark grey highlights tet(M) sequences. Sequence comparison between the tet(S/M)-containing circle and nucleotides 25513–29826 of Lc. lactis plasmid pK214 (accession no. X92946) is shown below the circle. Percentage homology is shown for each coding and non-coding subregion.
